Deuteronomy 12:5-7 establishes bringing firstborn to the chosen place to eat and rejoice — directly echoing the annual feast of firstborn.

In Deuteronomy 12:17, the same restriction applies: sacred offerings like firstborn must be eaten only at the sanctuary, not in one's towns.

In Deuteronomy 12:7, the joyful eating before the LORD at the sanctuary is described, directly paralleling the feast of firstborn here.

In Deuteronomy 12:18, eating sacred offerings with your household at the sanctuary and rejoicing is echoed, closely matching this verse.

In Deuteronomy 14:23, the tithe and firstborn are to be eaten before the LORD at the chosen place, mirroring this annual feast command.
