Yea, mine own familiar friend, in whom I trusted, which did eat of my bread, {g} hath lifted up his heel against me.

(g) As David felt this falsehood, and as it was chiefly accomplished in Christ, Joh 13:18 so shall his members continually prove the same.

Wesley's Notes

41:9 Yea - These words were literally fulfilled in David, and yet the Holy Ghost looked farther in them, even to Christ and Judas, in whom they received a fuller accomplishment. Lift up - A phrase implying injury, joined with insolency and contempt; taken from an unruly horse, which kicks at him that owns and feeds him.

King James Translators' Notes

mine...: Heb. the man of my peace

lifted...: Heb. magnified

Jamieson-Fausset-Brown Bible Commentary

9. mine . friend-literally, "the man of my peace."

eat . bread-who depended on me or was well treated by me.

hath lifted up heel-in scornful violence. As David and his fortunes typified Christ and His (compare [586]Introduction), so these words expressed the treatment he received, and also that of his Son and Lord; hence, though not distinctly prophetical, our Saviour (Joh 13:18) applies them to Judas, "that the Scripture may be fulfilled." This last phrase has a wide use in the New Testament, and is not restricted to denote special prophecies.

Matthew Henry's Concise Commentary

41:5-13 We complain, and justly, of the want of sincerity, and that there is scarcely any true friendship to be found among men; but the former days were no better. One particularly, in whom David had reposed great confidence, took part with his enemies. And let us not think it strange, if we receive evil from those we suppose to be friends. Have not we ourselves thus broken our words toward God? We eat of his bread daily, yet lift up the heel against him. But though we may not take pleasure in the fall of our enemies, we may take pleasure in the making vain their designs. When we can discern the Lord's favour in any mercy, personal or public, that doubles it. If the grace of God did not take constant care of us, we should not be upheld. But let us, while on earth, give heartfelt assent to those praises which the redeemed on earth and in heaven render to their God and Saviour.
