Jacob's hope

Why Jacob? How did the selfish deceiver get this kind of endorsement? I was reading Psalm 146 and found this:

Happy are those whose help is the God of Jacob... (Psalms 146:5)

I get the part about being happy because we have God's help but why is He called the God of Jacob? Why not the God of Moses or Abraham or Noah?

Jacob was the grandson of Abraham, a wayward young man who deceived his brother and his father for selfish gain. He was a liar and a coward, running from the consequences of his deceptions.

Why would God identify himself with Jacob?

What did the God of Jacob do? He kept his promise to Jacob when Jacob kep no promise with God. The Lord sustained Jacob when he deserved death, remembering the covenant made with his grandfather, Abraham. Jacob cared only for birthrights and blessings for personal gain.

God reached out when Jacob could not and would not. God made the covenant and chose to keep even Jacob's side of it.

A former deceiver was changed into a patriarch who fathered the twelve tribes of Israel - with a new name revealing a new character.

Jacob deserved to see his plans flame out like a falling star but instead God sustained His plans.

No wonder those whose help is the God of Jacob are happy. Their hope is beyond their own worth or activity.

The Lord's plans are eternal. He remembers His promises even when we do not. God extends a one-sided arrangement that is astonishingly gracious. That's hope.

Do not put your trust in princes, in mortals, in whom there is no help. When their breath departs, they return to the earth; on that very day their plans perish. Happy are those whose help is the God of Jacob, whose hope is in the Lord their God,
Psalms 146:3-5
