The chapter
Simply The middle of the sermon. Three religious habits are handled the same way, giving, praying and fasting, each to be done out of sight; the prayer he teaches sits in the middle of them; and the chapter ends on money, food and clothing, and on not being afraid about them.
Context The shape repeats so exactly that it is hard to miss: do not do it to be seen, the hypocrites already have their reward, do it in secret, and your Father who sees in secret will reward you. Three times, with the practice swapped out.
Verses 9-13
Simply The prayer: a father addressed, a name kept holy, a kingdom asked for, bread for today, forgiveness tied to forgiving, and a request not to be brought to the test.
Context Two things about this prayer can be checked in the app rather than taken on trust. FIRST, THE ENDING. Eleven of the thirteen editions offered here close verse 13 with a doxology, for yours is the kingdom and the power and the glory; two do not and simply stop at deliverance, the Riveduta and the Statenvertaling. SECOND, LUKE'S SHORTER VERSION. Luke gives the same prayer, and how much shorter it is depends on the edition: nine of the thirteen have Luke matching Matthew closely, and four give a markedly shorter Luke that begins simply Father and drops the clause about the will being done, the Riveduta, Statenvertaling, Viet 1934 and Segond 1910. The two French editions differ from each other here as they do at Matthew 3:11. Notice also that the same two editions do both things, dropping the doxology and shortening Luke.
Verses 14-18
Simply Immediately after the prayer he returns to one line of it: if you forgive others, your Father will forgive you, and if you do not, he will not. Then fasting, with the same rule of secrecy, and an instruction to wash and look ordinary.
Context Of the whole prayer this is the only clause he stops to expand, and he expands it in both directions rather than one. The fasting instruction is practical and slightly comic: the mark of fasting is to look exactly as you look on any other day.
Verses 19-24
Simply Do not store treasure where moth and rust eat it and thieves dig through for it. Where your treasure is, your heart will be. Nobody can serve two masters.
Context The argument is about attention rather than about poverty: the heart follows the treasure, and the eye either lets light into the whole body or does not. The three images are stacked without connectives, treasure, eye, two masters, and only the last of them names what the rival is.
Verses 25-34
Simply Do not be anxious about food or clothing. Look at the birds, which do not sow or reap and are fed; look at the wild flowers, which do not work or spin and are dressed better than Solomon.
Context Both examples are drawn from what is outside the door rather than from scripture, and both are arguments from the smaller to the greater. The grass he points at is fuel: it exists today and tomorrow goes into the oven, which is why the clothing of it is an argument at all. The chapter closes by shrinking the horizon rather than widening it, to today.
