Proverbs 26:25

And when he comes to see me, he speaks worthlessness; His heart gathers wickedness to itself; When he goes outside, he speaks it.

For as he calculates in his soul, so he is. “Eat and drink!” he says to you, But his heart is not with you.

“Let everyone beware of his neighbor, And do not trust any brother, Because every brother surely supplants, And every neighbor goes about as a slanderer.

“For even your brothers and the household of your father, Even they have dealt treacherously with you, Even they have called aloud after you. Do not believe them, although they may say nice things to you.”
