Jesus regarded his followers prior to Calvary and Easter as still “in Egypt,” and I propose that the Lord’s Prayer was designed to constitute them as “Exodus People,” “Freedom People” — indeed, as “New Covenant People.”
I would encourage you read to through the Sermon on The Mount, particularly the Lord’s Prayer, in light of its similarities and Jesus’s fulfillment of the promises of the Old Testament as a New Moses who would lead his people out of bondage into the Promised Land.
See an example below:
Give Us Today Our Daily Bread
The prayer for bread has its historical background in the provision of manna in the wilderness. God’s daily gift, following the people’s grumbling, became the stuff of legend. Jesus’ actions in the feeding miracles alluded to the wilderness stories, as the evangelists (especially John) suggest. In the context of the Lord’s Prayer, this clause aligns the followers of Jesus with the wilderness generation and their need to know God’s daily supply of not only literal bread but also of all that it symbolized.
Manna was not needed in Egypt, in bondage they were under the watch and keeping of their King. Nor would it be needed in the promised land. It is the food of inaugurated eschatology, that is the food of the sojourner, the food that is needed because the kingdom has already broken in, so the people find themselves dependent upon God’s gracious provision and because it is not yet consummated. The daily provision of manna signals that the Exodus has begun, but also that we are not yet living in the land.
