The man’s name was Elimelech and his wife’s name was Naomi and his two sons were named Mahlon and Chilion. They were Ephrathites from Bethlehem in Judah. They went to the country of Moab and stayed there.

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.”

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].
