1Now these are the last words of David.
David the son of Jesse says,
the man who was raised on high says,
the anointed of the God of Jacob,
the sweet psalmist of Israel:
2“Yahweh’s Spirit spoke by me.
His word was on my tongue.
3The God of Israel said,
the Rock of Israel spoke to me,
‘One who rules over men righteously,
who rules in the fear of God,
4shall be as the light of the morning when the sun rises,
a morning without clouds,
when the tender grass springs out of the earth,
through clear shining after rain.’
5Isn’t my house so with God?
Yet he has made with me an everlasting covenant,
ordered in all things, and sure,
for it is all my salvation and all my desire.
Won’t he make it grow?
6But all the ungodly will be as thorns to be thrust away,
because they can’t be taken with the hand.
7The man who touches them must be armed with iron and the staff of a spear.
They will be utterly burned with fire in their place.”
8These are the names of the mighty men whom David had: Josheb Basshebeth a Tahchemonite, chief of the captains; he was called Adino the Eznite, who killed eight hundred at one time. 9After him was Eleazar the son of Dodai the son of an Ahohite, one of the three mighty men with David when they defied the Philistines who were there gathered together to battle, and the men of Israel had gone away. 10He arose and struck the Philistines until his hand was weary, and his hand froze to the sword; and Yahweh worked a great victory that day; and the people returned after him only to take plunder. 11After him was Shammah the son of Agee a Hararite. The Philistines had gathered together into a troop where there was a plot of ground full of lentils; and the people fled from the Philistines. 12But he stood in the middle of the plot and defended it, and killed the Philistines; and Yahweh worked a great victory.
13Three of the thirty chief men went down, and came to David in the harvest time to the cave of Adullam; and the troop of the Philistines was encamped in the valley of Rephaim. 14David was then in the stronghold; and the garrison of the Philistines was then in Bethlehem. 15David said longingly, “Oh that someone would give me water to drink from the well of Bethlehem, which is by the gate!”
16The three mighty men broke through the army of the Philistines, and drew water out of the well of Bethlehem that was by the gate and took it and brought it to David; but he would not drink of it, but poured it out to Yahweh. 17He said, “Be it far from me, Yahweh, that I should do this! Isn’t this the blood of the men who risked their lives to go?” Therefore he would not drink it. The three mighty men did these things.
18Abishai, the brother of Joab, the son of Zeruiah, was chief of the three. He lifted up his spear against three hundred and killed them, and had a name among the three. 19Wasn’t he most honorable of the three? Therefore he was made their captain. However he wasn’t included as one of the three.
20Benaiah the son of Jehoiada, the son of a valiant man of Kabzeel, who had done mighty deeds, killed the two sons of Ariel of Moab. He also went down and killed a lion in the middle of a pit in a time of snow. 21He killed a huge Egyptian, and the Egyptian had a spear in his hand; but he went down to him with a staff and plucked the spear out of the Egyptian’s hand, and killed him with his own spear. 22Benaiah the son of Jehoiada did these things, and had a name among the three mighty men. 23He was more honorable than the thirty, but he didn’t attain to the three. David set him over his guard.
24Asahel the brother of Joab was one of the thirty: Elhanan the son of Dodo of Bethlehem, 25Shammah the Harodite, Elika the Harodite, 26Helez the Paltite, Ira the son of Ikkesh the Tekoite, 27Abiezer the Anathothite, Mebunnai the Hushathite, 28Zalmon the Ahohite, Maharai the Netophathite, 29Heleb the son of Baanah the Netophathite, Ittai the son of Ribai of Gibeah of the children of Benjamin, 30Benaiah a Pirathonite, Hiddai of the brooks of Gaash. 31Abialbon the Arbathite, Azmaveth the Barhumite, 32Eliahba the Shaalbonite, the sons of Jashen, Jonathan, 33Shammah the Hararite, Ahiam the son of Sharar the Ararite, 34Eliphelet the son of Ahasbai, the son of the Maacathite, Eliam the son of Ahithophel the Gilonite, 35Hezro the Carmelite, Paarai the Arbite, 36Igal the son of Nathan of Zobah, Bani the Gadite, 37Zelek the Ammonite, Naharai the Beerothite, armor bearers to Joab the son of Zeruiah, 38Ira the Ithrite, Gareb the Ithrite, 39and Uriah the Hittite: thirty-seven in all.
Jacob was the son of Isaac and Rebekah, born immediately after Esau, and Abraham was his grandfather. He achieved the right of the firstborn by trickery, in offering his older brother, Esau, food in exchange for the birthright, who cared little for this position. He also received the blessing of firstborn from his father Jacob before his death by cunning, and with the assistance of his mother Rebekah.
After his deception of Esau, receiving the blessing from his father, Jacob escaped to his uncle Laban, who in turn deceived Jacob into working for fourteen years for the marriage of Jacob to Leah, and then his beloved Rachel. Laban also sought to deceive Jacob of wages, but God intervened to ensure he would prosper. In a time of trial, when he feared the wrath of Esau, upon returning to the land of Canaan, Jacob had an encounter with God, and his name was changed to Israel, the one who wrestles with God. Even though his early life was characterized by deception, God worked through the situation to ensure that Jacob would be the one in the line of the patriarchs, to create a great nation and ultimately fulfill His purposes in the earth, especially through the future Messiah. The Messiah would guarantee the promise of the land to Abram and a person who would rule over Abraham's descendants, but also He would bring blessings to all the people of the earth (Gen 12:1-3).
In spite of Jacob's early failure by deception, God worked through him, and finally, Jacob became a different type of man after his struggle with God. As one has said,
"Despite Jacob’s faults, God chose him to be the leader of a great nation that still bears his name today. But for this, it is unlikely that we would know much about Jacob, who appears to be in the middle of events while the key players are those around him. There is no great wisdom or bravery in Jacob to speak of, and we are tempted to see him as little more than God’s passive instrument. If we are tempted to think that, because we aren’t in the spotlight performing great acts for God, we are unimportant to Him, then we should consider the life of Jacob and know that, in spite of our failings, God can and will still use us in His plan."
