{And it was} in the fortieth year, on the eleventh month, on [the] first [day] of the month, Moses spoke to the {Israelites} according to all that Yahweh had instructed him [to speak] to them.

And you shall remember all [of] the way that Yahweh your God led you [during] these forty years in the desert in order to humble you and to test you to know what [is] in your heart, whether you would [diligently] keep his commandments or not.

Your clothes

Your clothing did not wear out {on you}, and your feet did not swell [during] these forty years.

Forty years you sustained them in the desert--they were not in need. Their clothing did not wear out and their feet did not swell.

Therefore do not be anxious, saying, 'What will we eat?' or 'What will we drink?' or 'What will we wear?,'

And thy shoe

The sandals on their feet [were] patched and old, their clothes [were] old, and their food was dry and crumbled.

Do not [take] a traveler's bag for the road, or two tunics, or sandals, or a staff, for the worker [is] deserving of his provisions.
