'Profitable' in the Bible

but whoever causes one of these little ones who believe in Me to stumble and sin [by leading him away from My teaching], it would be better for him to have a heavy millstone [as large as one turned by a donkey] hung around his neck and to be drowned in the depth of the sea.

“If your hand or your foot causes you to stumble and sin, cut it off and throw it away from you [that is, remove yourself from the source of temptation]; it is better for you to enter life crippled or lame, than to have two hands or two feet and be thrown into everlasting fire.

If your eye causes you to stumble and sin, pluck it out and throw it away from you [that is, remove yourself from the source of temptation]; it is better for you to enter life with only one eye, than to have two eyes and be thrown into the fiery hell.

The disciples said to Jesus, “If the relationship of a man with his wife is like this, it is better not to marry.”

The Son of Man is to go [to the cross], just as it is written [in Scripture] of Him; but woe (judgment is coming) to that man by whom the Son of Man is betrayed! It would have been good for that man if he had never been born.”
