“You shall count seven weeks for yourself.” With that simple command in Deuteronomy 16, Moses opens up one of the richest feasts in Israel’s calendar.

The Feast of Weeks was not an arbitrary religious holiday, and it was not merely a harvest party with some pious decorations added on top. God appointed it to teach His people how to remember, how to rejoice, how to give thanks, how to care for the poor, and ultimately how to understand what He would later accomplish in Christ at Pentecost.

If we read these Old Testament feasts carelessly, we can treat them as little more than ancient Israelite scheduling. But Moses was not filling space. These feasts had design, order, and theological weight. They were shadows, and Christ is the substance. They were appointed signs, and in the New Testament their meaning bursts into full bloom.
