'Requires' in the Bible

It shall be when these signs come to you, do for yourself what the occasion requires, for God is with you.

And may these words of mine, with which I have made supplication before the Lord, be near to the Lord our God day and night, that He may maintain the cause of His servant and the cause of His people Israel, as each day requires,

“For what is the hope of the godless when he is cut off,When God requires his life?

For He who requires blood remembers them;He does not forget the cry of the afflicted.

“When you come to appear before Me,Who requires of you this trampling of My courts?
