Proverbs 20:16 Take his garment that is surety for a stranger: and take a pledge of him for a strange woman.
17 Bread of deceit is sweet to a man; but afterwards his mouth shall be filled with gravel.
We begin here seeing again that we should be careful about taking on the burden of someone else debt. Back in biblical times it was customary to offer a garment to cove a debt. Today if we stand for someone else debt it usually costs a lot more and so it is not a good practice.The second part of this verse making sure you have what is needed to take care of a stranger, this refers to a woman but it could be for anyone. Next verse tells us the bread of deceit, on how good it taste when we partake of it, but the effects of it afterwards leaves us feeling the results of sin. Sin seems to be pleasure, but the end is sorrow and regret. The last part of this verse sounds a little like what happens in hell where there is gnashing of teeth. Let us strive each day to be aware of the ways God wants us to deal with people and know enough of His word that we not easily deceived.
