'Shouldest' in the Bible

And Jehu the son of Hanani, the seer, went out to meet him, and said to king Jehoshaphat, Shouldest thou help the ungodly, and love them that hate Jehovah? Therefore is wrath upon thee from Jehovah.

And it came to pass as he talked with him, that Amaziah said to him, Hast thou been made the king's counsellor? Forbear; why shouldest thou be smitten? Then the prophet forbore, and said, I know that God has determined to destroy thee, because thou hast done this, and hast not hearkened to my counsel.

Thou thinkest, Lo, thou hast smitten Edom; and thy heart has lifted thee up to boast: abide now at home; why shouldest thou contend with misfortune, that thou shouldest fall, thou and Judah with thee?
