'Shouldest' in the Bible

And the man of God was wroth with him, and said, Thou shouldest have smitten five or six times; then wouldest thou have smitten the Syrians till thou hadst consumed them; whereas now thou shalt smite Syria but thrice.

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

Hast thou not heard long ago that I have done it? And that from ancient days I formed it? Now have I brought it to pass, that thou shouldest lay waste fortified cities into ruinous heaps.
