Nehemiah 9:14
And madest known unto them thy holy sabbath, and commandedst them precepts, statutes, and laws, by the hand of Moses thy servant: And madest known unto them thy holy sabbath, and commandedst them precepts, statutes, and laws, by the hand of Moses thy servant:
God made His holy Sabbath known to Israel and commanded precepts, statutes, and laws by the hand of Moses His servant, as part of the instruction He gave at Sinai. The One who made the Sabbath known and gave the commands through Moses was Christ, acting as Israel's Redeemer, Protector, and wonder-working God. That giving took place when Christ Himself came down on Mount Sinai and spoke from heaven, giving right judgments and true laws, good statutes and commandments.
That same care for Israel in the wilderness included dividing the sea and leading them by the cloudy pillar by day and the pillar of fire by night. It included giving bread from heaven and water from the rock, giving His good Spirit to instruct them, and sustaining them forty years so that they lacked nothing. In Nehemiah 9 the verse belongs to the retelling of the Lord's works for His people, including the public reading of the Book of the Law and the making known of God's requirements, set within a history of God's goodness met by the people's ingratitude, punishment, and acknowledgment that God's dealings were just.
The public opening of the Book of the Law of Moses took place with Ezra standing on a raised wooden platform holding the open book before a large assembly of attentive men gathered in a street in Jerusalem among ruined buildings, with the Ten Commandments set forth on either side as the substance of that law. The miracles and guidance did not save them, because they dealt proudly, hardened their necks, refused to obey, and would not walk in obedience to His will, yet their later rebellion and rejection of His law did not erase the guidance and wonders He had given them. The people's turning from God separated them from God and led Him to permit them to be brought under the control of heathen nations.
The people responded by covenanting to obey God's law given through Moses, making their promise a written, signed memorial to remind them of their duty and guard them against temptation, including an oath not to intermarry with the peoples of the land. The history of receiving God's favor recounted in the verse applies to Seventh-day Adventists, who also received great truths and favors but did not always appreciate them or give God the glory.
