Albert Barnes Commentary Hebrews 13:5

"Be ye free from the love of money; content with such things as ye have: for himself hath said, I will in no wise fail thee, neither will I in any wise forsake thee." — Hebrews 13:5 (ASV)

Let your conversation. Your conduct—for that is how the word 'conversation' is used in the Scriptures. See Barnes on Philippians 1:27.

Be without covetousness. See Barnes on Ephesians 5:3 and Colossians 3:5.

And be content with such things as ye have. See Barnes on Philippians 4:11-12 and Matthew 6:25 and following. The particular reason given here for contentment is that God has promised never to leave his people. Compare with this the beautiful argument of the Saviour in Matthew 6:25 and following.

For he hath said. That is, God has said.

I will never leave thee, nor forsake thee. See Deuteronomy 31:6; Joshua 1:5; 1 Chronicles 28:20; Genesis 28:15. Substantially the same expression is found in each of those places, and all of them contain the principle on which the apostle here relies: that God will not forsake his people.
