'Weak' in the Bible

For while we were yet weak, at the right time Christ died for the ungodly.

For what the law couldn't do, in that it was weak through the flesh, God did, sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh;

Now accept one who is weak in faith, but not for disputes over opinions.

One man has faith to eat all things, but he who is weak eats only vegetables.

It is good to not eat meat, drink wine, nor do anything by which your brother stumbles, is offended, or is made weak.

Now we who are strong ought to bear the weaknesses of the weak, and not to please ourselves.
