Proverbs 5:10

Lest strangers be satisfied by your strength

And by your painful labor, those in the house of a foreigner;

Proverbs 6:1

My son, if you have become a guarantor for your neighbor,

Have struck your hands in pledge for a stranger,

If one becomes a guarantor for a stranger, he will surely suffer,

But he who hates striking hands in pledge is secure.

Take his garment when he becomes a guarantor for a stranger;

And for foreigners, hold him in pledge.
