For the Chief Musician. On an instrument of Gath. By Asaph.
1Sing aloud to God, our strength!
Make a joyful shout to the God of Jacob!
2Raise a song, and bring here the tambourine,
the pleasant lyre with the harp.
3Blow the trumpet at the New Moon,
at the full moon, on our feast day.
4For it is a statute for Israel,
an ordinance of the God of Jacob.
5He appointed it in Joseph for a covenant,
when he went out over the land of Egypt,
I heard a language that I didn’t know.
6“I removed his shoulder from the burden.
His hands were freed from the basket.
7You called in trouble, and I delivered you.
I answered you in the secret place of thunder.
I tested you at the waters of Meribah.” Selah.
8“Hear, my people, and I will testify to you,
Israel, if you would listen to me!
9There shall be no strange god in you,
neither shall you worship any foreign god.
10I am Yahweh, your God,
who brought you up out of the land of Egypt.
Open your mouth wide, and I will fill it.
11But my people didn’t listen to my voice.
Israel desired none of me.
12So I let them go after the stubbornness of their hearts,
that they might walk in their own counsels.
13Oh that my people would listen to me,
that Israel would walk in my ways!
14I would soon subdue their enemies,
and turn my hand against their adversaries.
15The haters of Yahweh would cringe before him,
and their punishment would last forever.
16But he would have also fed them with the finest of the wheat.
I will satisfy you with honey out of the rock.”
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."
