Leviticus 23:10 establishes the wave sheaf offering that marks the starting day for the count here in 23:15.

Leviticus 23:11 defines the 'day after the Sabbath' when the priest waves the sheaf — the same day from which the count in 23:15 begins.

In Leviticus 25:8, the same seven-sabbath pattern applies to jubilee years—a different context but the counting principle is identical.

Exodus 34:22 names the Feast of Weeks, the same festival described here—the counting leads to the wheat harvest celebration.

Deuteronomy 16:9 echoes this counting instruction: 'seven weeks you shall count' from the sickle to the grain harvest.

Deuteronomy 16:10 follows the count with the Feast of Weeks offering—this verse completes the festival preparation.

Numbers 28:26 prescribes the offerings for the day of firstfruits, the culmination of the seven-week count.

Acts 2:1 records Pentecost, the exact fulfillment of the fifty-day count—the Spirit came on the Feast of Weeks.

1 Corinthians 16:8 shows Paul timing his travels around Pentecost, confirming the festival's continued observance.
