'Least' in the Bible

Naaman said, “If not, please let your servant at least be given two mules’ load of earth; for your servant will no longer offer burnt offering nor will he sacrifice to other gods, but to the Lord.

How then wilt thou turn away the face of one captain of the least of my master's servants, and put thy trust on Egypt for chariots and for horsemen?

Hezekiah said to Isaiah, "The Lord's word which you have announced is appropriate." Then he added, "At least there will be peace and stability during my lifetime."
