'Regarding' in the Bible

regarding his Son. He was a descendant of David with respect to his humanity

What then shall we say that Abraham, our ancestor according to the flesh, has discovered regarding this matter?

So even David himself speaks regarding the blessedness of the man to whom God credits righteousness apart from works:

For example, a married woman is legally bound to her husband while he lives. But if her husband dies, she is released from the law regarding the husband.

Regarding the gospel, they are enemies for your advantage, but regarding election, they are loved because of the patriarchs,

He who is regarding the day, to the Lord he doth regard it, and he who is not regarding the day, to the Lord he doth not regard it. He who is eating, to the Lord he doth eat, for he doth give thanks to God; and he who is not eating, to the Lord he doth not eat, and doth give thanks to God.

Therefore I have reason to boast in Christ Jesus regarding what pertains to God.
