John Gill Commentary Deuteronomy 4:45

"these are the testimonies, and the statutes, and the ordinances, which Moses spake unto the children of Israel, when they came forth out of Egypt," — Deuteronomy 4:45 (ASV)

These are the testimonies, and the statutes, and the
judgments
The laws, moral, ceremonial, and judicial, delivered in the following chapters; which are renewed, repeated, and explained: which Moses spoke to the children of Israel, after they came forth out of Egypt; in the third month after they came from there these laws were delivered to him at Mount Sinai, and he declared them to them; and now afresh, near forty years after, repeated them to them in the plains of Moab.
