In a footnote to this translation Mr. Fenton says:
The above is the literal translation of the original Greek, retaining the Greek moods and tenses by the clearest English I could. The old versions, having been made from a Latin translation, could not reproduce the actual sense of the Saviour as given by the Evangelists, for Latin has no Aorist of the imperative passive mood used by Matthew and Luke.
The force of the imperative first Aorist seems to me to be that of what is called a standing order, a thing to be done absolutely, and continuously.
Ferrar Fenton says that the Aorist is a tense expressing complete action in a single movement. So we see that according to the preface of the Lord's Prayer as originally given by Jesus, He wants us not to pray for something to be done in the future. Instead, since God has already provided the things we need before we ask Him, our prayers should be in the nature of a command implying our recognition of the fact that they are now appearing in our world. As Fenton says, the prayer is of the nature of a standing order, "a thing to be done absolutely, and continuously."
So we see that we are not to beg God to provide for us, implying that He has been like an improvident parent whom we have to remind of His remissness. God has provided absolutely and continuously for every need of man, individually and collectively, and everything belongs to us: "All things whatsoever the Father hath are mine," said Jesus.
