Deuteronomy 27:1

And Moses with the elders of Israel commanded the people, saying, Keep all the commandments which I command you this day.

Moses acted together with the elders of Israel to charge the people to keep all the commandments given that day. The charge was given as Israel was about to cross the Jordan into the promised land to take possession of their inheritance, as a renewal of covenant loyalty to be solemnly recognized at Mounts Ebal and Gerizim. In connection with the charge, Israel was to preserve the words of the law very plainly upon plastered stones, build an altar, offer sacrifices, rejoice before the Lord, and obey the Lord as His people.

The commanding voice was not merely human but Christ Himself speaking from the enfolding pillar of cloud, speaking with His own voice so that the important directions would not be forgotten. What was commanded was to keep all His statutes, judgments, and commandments with all the heart and with all the soul, expressing the principles of the law of the kingdom of God and making His claims clear and specific so that minds are not left in ignorance and uncertainty. Together with Deuteronomy 26 and 28 and the surrounding chapters, the directions set out plainly the blessings of obedience, reminding the people that obedience is for their present and future good and brings prosperity and blessing, while disobedience results in a curse.

The claim lays a never-ceasing obligation on all whom God has blessed with life and health and temporal and spiritual advantages to publicly acknowledge His favor, and it is just as binding and fresh now as when it was given because God's gifts are fresh and continual, so that God's name will be glorified as a testimony that His Word is verity and truth. The commandments were to remain continually before the people by being written down, repeated at stopping places and during travel, and taught to children, and this repetition reminded Israel of the consequences of disobedience and helped keep the people faithful. In connection with keeping the people faithful, Moses's own failure meant that he could not lead them into the promised land.
