'Timid' in the Bible

And the officers shall speak further unto the people, and shall say, What man is there that is timid and faint-hearted? let him go and return unto his house, lest his brethren's heart melt as well as his heart.

And Elihu the son of Barachel the Buzite answered and said, I am young, and ye are aged; wherefore I was timid, and feared to shew you what I know.

Say to them that are of a timid heart, Be strong, fear not; behold your God: vengeance cometh, the recompense of God! He will come himself, and save you.
