'Weak' in the Bible

How weak is thy heart, An affirmation of the Lord Jehovah, In thy doing all these, The work of a domineering whorish woman.

and it hath come to pass, when they say unto thee, For what art thou sighing? that thou hast said: Because of the report, for it is coming, And melted hath every heart, And feeble hath been all hands, And weak is every spirit, And all knees go -- waters, Lo, it is coming, yea, it hath been, An affirmation of the Lord Jehovah.'

The weak ye have not strengthened, And the sick one ye have not healed, And the broken ye have not bound up, And the driven away have not brought back, And the lost ye have not sought, And with might ye have ruled them and with rigour.
