Leviticus 23:2 introduces the feasts as holy convocations, providing the framework for the specific command in verse 25.

Leviticus 23:35 applies the same 'holy convocation, no servile work' rule to the Feast of Tabernacles, showing the pattern across feasts.

Numbers 29:1 describes the same Feast of Trumpets with identical wording — holy convocation, no servile work — as a parallel account.

Exodus 12:16 also commands a holy convocation with no servile work (except food preparation) for the Passover/Unleavened Bread, paralleling this restriction.

Numbers 28:25 similarly commands a holy convocation with no servile work for the seventh day of Unleavened Bread, paralleling this rule.
