'Shouldest' in the Bible

If therefore thou shouldest offer thy gift at the altar, and there shouldest remember that thy brother has something against thee,

And the centurion answered and said, Lord, I am not fit that thou shouldest enter under my roof; but only speak a word, and my servant shall be healed.

shouldest not thou also have had compassion on thy fellow-bondman, as I also had compassion on thee?
