Leviticus 23:23-25

Amplified Bible, Classic Edition

²³ And the Lord said to Moses,

²⁴ Say to the Israelites, On the first day of the seventh month [almost October], you shall observe a day of solemn [sabbatical] rest, a memorial day announced by blowing of trumpets, a holy [called] assembly.

²⁵ You shall do no servile work on it, but you shall present an offering made by fire to the Lord.
