1Now you shall gather yourself in troops,
daughter of troops.
He has laid siege against us.
They will strike the judge of Israel with a rod on the cheek.
2But you, Bethlehem Ephrathah,
being small among the clans of Judah,
out of you one will come out to me who is to be ruler in Israel;
whose goings out are from of old, from ancient times.
3Therefore he will abandon them until the time that she who is in labor gives birth.
Then the rest of his brothers will return to the children of Israel.
4He shall stand, and shall shepherd in the strength of Yahweh,
in the majesty of the name of Yahweh his God.
They will live, for then he will be great to the ends of the earth.
5He will be our peace when Assyria invades our land
and when he marches through our fortresses,
then we will raise against him seven shepherds,
and eight leaders of men.
6They will rule the land of Assyria with the sword,
and the land of Nimrod in its gates.
He will deliver us from the Assyrian,
when he invades our land,
and when he marches within our border.
7The remnant of Jacob will be among many peoples
like dew from Yahweh,
like showers on the grass,
that don’t wait for man
nor wait for the sons of men.
8The remnant of Jacob will be among the nations,
among many peoples,
like a lion among the animals of the forest,
like a young lion among the flocks of sheep;
who, if he goes through, treads down and tears in pieces,
and there is no one to deliver.
9Let your hand be lifted up above your adversaries,
and let all of your enemies be cut off.
10“It will happen in that day”, says Yahweh,
“that I will cut off your horses from among you
and will destroy your chariots.
11I will cut off the cities of your land
and will tear down all your strongholds.
12I will destroy witchcraft from your hand.
You shall have no soothsayers.
13I will cut off your engraved images and your pillars from among you;
and you shall no more worship the work of your hands.
14I will uproot your Asherah poles from among you;
and I will destroy your cities.
15I will execute vengeance in anger
and wrath on the nations that didn’t listen.”
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."
