'Shouldest' in the Bible

Lest thou shouldest ponder the path of life, her ways are moveable, that thou canst not know them.

For better it is that it be said unto thee, Come up hither; than that thou shouldest be put lower in the presence of the prince whom thine eyes have seen.

Though thou shouldest bray a fool in a mortar among wheat with a pestle, yet will not his foolishness depart from him.
