Albert Barnes Commentary Job 22:27

"Thou shalt make thy prayer unto him, and he will hear thee; And thou shalt pay thy vows." — Job 22:27 (ASV)

Thou shalt make thy prayer unto him - God would then hear him, for he would be righteous. This was one of the blessings which would follow reconciliation. It is, in fact, one of the blessings of a return to God. He hears the cry of his people, and answers their supplications. To be permitted to go to God and to tell him all our needs, to plead for all we need and to implore blessings on our families and friends, is a privilege of far higher value than anything which wealth can bestow; is worth more than all the honors of this world.

And thou shalt pay thy vows - That is, your vows shall be accepted; you shall obtain those blessings for which you made your vows.
