'Feeble' in the Bible

And not being feeble in faith though his body seemed to him little better than dead (he being about a hundred years old) and Sarah was no longer able to have children:

I am using words in the way of men, because your flesh is feeble: as you gave your bodies as servants to what is unclean, and to evil to do evil, so now give them as servants to righteousness to do what is holy.

For what the law was not able to do because it was feeble through the flesh, God, sending his Son in the image of the evil flesh, and as an offering for sin, gave his decision against sin in the flesh:

And in the same way the Spirit is a help to our feeble hearts: for we are not able to make prayer to God in the right way; but the Spirit puts our desires into words which are not in our power to say;

Do not put on one side him who is feeble in faith, and do not put him in doubt by your reasonings.

One man has faith to take all things as food: another who is feeble in faith takes only green food.

We who are strong have to be a support to the feeble, and not give pleasure to ourselves.
