'Faint hearted' in the Bible

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

And say to him, Take heed, and be quiet; fear not, neither be faint-hearted for the two tails of these smoking fire-brands, for the fierce anger of Rezin with Syria, and of the son of Remaliah.

Concerning Damascus. Hamath is confounded, and Arpad: for they have heard evil tidings: they are faint-hearted; there is sorrow on the sea; it cannot be quiet.
