'Feeble' in the Bible

And let the overseers go on to say to the people, If there is any man whose heart is feeble with fear, let him go back to his house before he makes the hearts of his countrymen feeble.

How, meeting you on the way, he made an attack on you when you were tired and without strength, cutting off all the feeble ones at the end of your line; and the fear of God was not in him.

And Moses at his death was a hundred and twenty years old: his eye had not become clouded, or his natural force become feeble.
