Luke 11:3

“Give us day by day our daily bread.] Or “for the day”; or “every day”, as the Syriac version renders it; (see Gill on “<400611>Matthew 6:11”)”

“day by day, &c.--an extension of the petition in Matthew for "this day's" supply, to every successive day's necessities. The closing doxology, wanting here, is wanting also in all the best and most ancient copies of Matthew's Gospel. Perhaps our Lord purposely left that part open: and as the grand Jewish doxologies were ever resounding, and passed immediately and naturally, in all their hallowed familiarity into the Christian Church, probably this prayer was never used in the Christian assemblies but in its present form, as we find it in Matthew, while in Luke it has been allowed to stand as originally uttered.”

“See this passage explained in the notes at Matthew 6:9-13. Luke 11:4 For we also forgive ... - This is somewhat different from the expression in Matthew, though the sense is the same. The idea is, that unless we forgive others, God will not forgive us; and unless we come to him “really” forgiving all others, we cannot expect pardon. It does not mean that by forgiving others we “deserve” forgiveness ourselves, or “merit it,” but that this is a disposition or state of mind without which God cannot consistently pardon us. Every one that is indebted to us - Every one that has “injured” us. This does not refer to pecuniary transactions, but to offences similar to those which “we” have committed…”

“Give: Exo 16:15-22; Pro 30:8; Isa 33:16; Mat 6:11, Mat 6:34; Joh 6:27-33 day by day: or, for the day Luke 11:4”
