1Yahweh, you God to whom vengeance belongs,
you God to whom vengeance belongs, shine out.
2Rise up, you judge of the earth.
Pay back the proud what they deserve.
3Yahweh, how long will the wicked,
how long will the wicked triumph?
4They pour out arrogant words.
All the evildoers boast.
5They break your people in pieces, Yahweh,
and afflict your heritage.
6They kill the widow and the alien,
and murder the fatherless.
7They say, “Yah will not see,
neither will Jacob’s God consider.”
8Consider, you senseless among the people;
you fools, when will you be wise?
9He who implanted the ear, won’t he hear?
He who formed the eye, won’t he see?
10He who disciplines the nations, won’t he punish?
He who teaches man knows.
11Yahweh knows the thoughts of man,
that they are futile.
12Blessed is the man whom you discipline, Yah,
and teach out of your law,
13that you may give him rest from the days of adversity,
until the pit is dug for the wicked.
14For Yahweh won’t reject his people,
neither will he forsake his inheritance.
15For judgment will return to righteousness.
All the upright in heart shall follow it.
16Who will rise up for me against the wicked?
Who will stand up for me against the evildoers?
17Unless Yahweh had been my help,
my soul would have soon lived in silence.
18When I said, “My foot is slipping!”
Your loving kindness, Yahweh, held me up.
19In the multitude of my thoughts within me,
your comforts delight my soul.
20Shall the throne of wickedness have fellowship with you,
which brings about mischief by statute?
21They gather themselves together against the soul of the righteous,
and condemn the innocent blood.
22But Yahweh has been my high tower,
my God, the rock of my refuge.
23He has brought on them their own iniquity,
and will cut them off in their own wickedness.
Yahweh, our God, will cut them off.
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."
