For the Chief Musician. On stringed instruments. A Psalm by Asaph. A song.
1In Judah, God is known.
His name is great in Israel.
2His tabernacle is also in Salem.
His dwelling place in Zion.
3There he broke the flaming arrows of the bow,
the shield, and the sword, and the weapons of war. Selah.
4Glorious are you, and excellent,
more than mountains of game.
5Valiant men lie plundered,
they have slept their last sleep.
None of the men of war can lift their hands.
6At your rebuke, God of Jacob,
both chariot and horse are cast into a dead sleep.
7You, even you, are to be feared.
Who can stand in your sight when you are angry?
8You pronounced judgment from heaven.
The earth feared, and was silent,
9when God arose to judgment,
to save all the afflicted ones of the earth. Selah.
10Surely the wrath of man praises you.
The survivors of your wrath are restrained.
11Make vows to Yahweh your God, and fulfill them!
Let all of his neighbors bring presents to him who is to be feared.
12He will cut off the spirit of princes.
He is feared by the kings of the earth.
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."
