'Feeble' in the Bible

All hands will be feeble and all knees without strength, like water.

How feeble is your heart, says the Lord, seeing that you do all these things, the work of a loose and overruling woman;

And when they say to you, Why are you making sounds of grief? then say, Because of the news, for it is coming: and every heart will become soft, and all hands will be feeble, and every spirit will be burning low, and all knees will be turned to water: see, it is coming and it will be done, says the Lord.

This is what the Lord has said: The day when he goes down to the underworld, I will make the deep full of grief for him; I will keep back her streams and the great waters will be stopped: I will make Lebanon dark for him, and all the trees of the field will be feeble because of him.
