Matthew 6:11

Give us this day our daily bread] We are not taught to pray for bread for many days, but for one day, God thereby reminding us of our continual dependence upon Him. Nor are we taught to pray for luxuries, but for bread, i.e. for necessary food, shelter, clothing, and health. We pray also for bread for our souls, i.e. the grace to confess our sins and to receive God's pardon, and to persevere, and to know God. But chiefly we pray that we may feed daily by faith on Jesus Christ, who is our true daily bread, and may be worthy partakers of the bread of blessing which makes us one with Him, and Him one with us, and which was to the first Christians literally their daily bread (Acts 2:46).

The Gk. word here translated 'daily' occurs nowhere else in Gk. literature, and its meaning is entirely unknown. The most likely meanings are, (1) daily bread, (2) tomorrow's bread, (3) heavenly bread. Probably the second is the true one, because the ancient Hebrew gospel of the Ebionites so understood it, perhaps preserving the original Heb. word used by Christ (Mahar).
