'Timid' in the Bible

and thou hast said unto him: 'Take heed, and be quiet, fear not, And let not thy heart be timid, Because of these two tails of smoking brands, For the fierceness of the anger of Rezin and Aram, And the son of Remaliah.

In that day the Egyptians will become like [helpless] women, and they will tremble and be frightened because of the waving of the hand of the Lord of hosts, which He is going to wave over them.

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.
