'Kept' in the Bible

This is what the LORD says: "For three transgressions of Edom and now for a fourth I will not turn away; because he pursued his brother with a sword, refusing to be compassionate. His anger was raging continuously; he kept up his unending wrath.

So I kept on saying, "Lord GOD, forgive please! How will Jacob stand, since he is so small?"

So Amaziah kept saying to Amos, "Get out of here, you seer! Go back to the land of Judah. Live there and prophesy there.

But the LORD took me from tending the flock and the LORD kept saying to me, "Go, prophesy to my people Israel.'
