'Invalid' in the Bible

where a woman was present who for eighteen years had been a confirmed invalid: she was bent double, and was unable to lift herself to her full height.

But it is easier [for] heaven and earth to pass away than [for] one stroke of a letter of the law to become invalid.

And there was one man there who had been an invalid for thirty-eight years.

The invalid answered, “Sir, I have no one to put me in the pool when the water is stirred up, and while I am coming [to get into it myself], someone else steps down ahead of me.”

Now the man who had been healed did not know who it was, for Jesus had slipped away [unnoticed] since there was a crowd in that place.

I do not declare invalid the grace of God, for if righteousness [is] through the law, then Christ died to no purpose.

Brothers, I am speaking according to a human perspective. Nevertheless, [when] the covenant of a man has been ratified, no one declares [it] invalid or adds additional provisions [to it].
