Salmos 139:19-22

19-22. From the foregoing survey of the divine perfections the psalmist draws unbounded consolation and hope for the righteous. He now, however, sees that the same causes secure the ultimate, inevitable punishment of the wicked. Sin, in the light of God, now appears “exceeding sinful;” and before the omniscience and omnipresence of God, cannot escape its desert. The transition of the poem at this point is abrupt, but natural, upon the laws of antithesis.

Surely The Hebrew is a strong asseveration. God will punish sin. It follows from his attributes.

Depart from me The author will have no alliance with the enemies of God. Their guilt and their ruin are, before him, alike abhorrent; on the other hand, the glory of God attracts him.
