Deuteronomy 1:3

And it came to pass in the fortieth year
That is, of the coming of the children of Israel out of Egypt:

in the eleventh month;
the month Shebet, as the Targum of Jonathan, which answers to part of January and part of February:

in the first day of the month, that Moses spoke unto the children of
Israel according to all that the Lord had given him in commandment unto
them;
repeated to them the several commandments, which the Lord had delivered to him at different times.
