For the Chief Musician. On an instrument of Gath. A Psalm by the sons of Korah.
1How lovely are your dwellings,
Yahweh of Armies!
2My soul longs, and even faints for the courts of Yahweh.
My heart and my flesh cry out for the living God.
3Yes, the sparrow has found a home,
and the swallow a nest for herself, where she may have her young,
near your altars, Yahweh of Armies, my King, and my God.
4Blessed are those who dwell in your house.
They are always praising you. Selah.
5Blessed are those whose strength is in you,
who have set their hearts on a pilgrimage.
6Passing through the valley of Weeping, they make it a place of springs.
Yes, the autumn rain covers it with blessings.
7They go from strength to strength.
Every one of them appears before God in Zion.
8Yahweh, God of Armies, hear my prayer.
Listen, God of Jacob. Selah.
9Behold, God our shield,
look at the face of your anointed.
10For a day in your courts is better than a thousand.
I would rather be a doorkeeper in the house of my God,
than to dwell in the tents of wickedness.
11For Yahweh God is a sun and a shield.
Yahweh will give grace and glory.
He withholds no good thing from those who walk blamelessly.
12Yahweh of Armies,
blessed is the man who trusts in you.
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."
