'Sought' in the Bible

I sought for a man among them, who should build up the wall, and stand in the gap before me for the land, that I should not destroy it; but I found none.

I will make you a terror, and you shall no more have any being; though you are sought for, yet you will never be found again, says the Lord Yahweh.

You haven't strengthened the diseased, neither have you healed that which was sick, neither have you bound up that which was broken, neither have you brought back that which was driven away, neither have you sought that which was lost; but with force and with rigor you have ruled over them.

My sheep wandered through all the mountains, and on every high hill: yes, my sheep were scattered on all the surface of the earth; and there was none who searched or sought.
