'Earnestly' in the Bible

Thou shalt not hate thy brother in thy heart; thou shalt earnestly rebuke thy neighbour, lest thou bear sin on account of him.

then I will remember My covenant with Jacob, and also My covenant with Isaac, and also My covenant with Abraham, and remember the land.

But I will, for their sake, [earnestly] remember the covenant with their forefathers, whom I have brought out of the land of Egypt in the sight of the nations, that I might be their God. I am the Lord.’”
