'Saying' in the Bible

wanting to be teachers of the law, [although they] do not understand either [the things] which they are saying or [the things] concerning which they are speaking confidently.

The saying [is] trustworthy and worthy of all acceptance: Christ Jesus came into the world to save sinners, of whom I am the foremost.

The saying [is] trustworthy: if anyone aspires to supervision, he desires a good work.

And at the same time also, going around from house to house, they learn [to be] idle, and not only idle, but also gossipy and busybodies, saying the things [that are] not necessary.
