The instructions in Deuteronomy 12 establish that all burnt offerings, sacrifices, tithes, and other worship elements must be brought exclusively to the central place the Lord chooses to place His name, rather than being offered wherever convenient. This requirement supersedes earlier instructions in Leviticus 23 regarding the wavesheaf offering and holds that such worship cannot occur until the people are dwelling in the land, at rest from enemies, and in safety, with the Tabernacle, altar, laver, and all associated furniture erected at the chosen site. The text develops this principle by noting that Israel crossed the Jordan and kept Passover in Joshua 5 while still engaged in conquest, without having reached settled conditions or constructed the required central sanctuary. Only after seven years, when the land was subdued and apportioned, did the congregation assemble at Shiloh to set up the Tabernacle of meeting, as recorded in Joshua 18:1, with full rest confirmed in Joshua 21:43-45. This sequence demonstrates that no legitimate offering, including any supposed wavesheaf ceremony, could have taken place upon entry into the land, because the central place of worship had not yet been established. The broader message connects this requirement directly to the proper observance of Pentecost by reinforcing that all festival ceremonies must follow the exact patterns and locations God assigns, preserving the weekly Sabbath within the Days of Unleavened Bread as the unchanging marker for beginning the count rather than allowing alterations based on assumptions about early offerings.

Deuteronomy 12 establishes that once Israel entered the Promised Land, all normal sacrificial worship, including the wavesheaf offering, had to occur at one central sanctuary chosen by God rather than at any location the people might select. Moses instructed the Israelites to destroy every pagan altar, pillar, and image in the land so that no trace of Canaanite worship would remain, then to bring their burnt offerings, sacrifices, tithes, and heave offerings exclusively to the place where the Lord would put His name. This requirement replaced the wilderness pattern, in which the Tabernacle could be erected wherever Israel camped for an extended period, and it served two overriding purposes: exclusive loyalty to the one true God and national unity centered on the religion He had given them. Because the central sanctuary could be established only after the land was conquered and rest from enemies was achieved, the Tabernacle was not set up until seven years after the Jordan crossing, when the congregation assembled at Shiloh. Until that time, the erection of any altar for ordinary worship was forbidden. Consequently, Joshua 5 records no altar, no priestly service, and no wavesheaf ceremony, since none of the required conditions had yet been met. The absence of these elements confirms that the Israelites could not have performed the firstfruits offering immediately after their first Passover in Canaan, regardless of the day of the week on which that Passover fell. This prohibition against local or premature sacrifices reinforces the principle that every detail of worship had to follow God's exact instructions if the nation was to remain holy and acceptable before Him.

In Deuteronomy 12 God gave Israel explicit instructions regarding offerings once the nation entered the promised land. The people were commanded to destroy all pagan worship sites and to bring their burnt offerings, sacrifices, tithes, heave offerings, vows, freewill offerings, and firstlings exclusively to the place the LORD would choose out of all the tribes to put His name and cause His habitation to dwell. This central location would serve as the sole site for national worship and rejoicing before God. Until that place was designated and the tabernacle erected there, the Israelites were forbidden to offer burnt offerings or perform the other regular ceremonial sacrifices in every location they might see or wherever seemed right in their own eyes. The instructions emphasized that these requirements would take effect after the people crossed the Jordan, received rest from their enemies, and dwelt in safety. The tabernacle was ultimately set up at Shiloh in the territory of Ephraim only after the land had been subdued and the remaining tribes had received their inheritance, approximately seven years after the initial entry. This regulation established a unified national religion under one headquarters rather than permitting decentralized or individual practices. The requirement for a central place of worship directly explains why no wave sheaf offering, burnt offering, meal offering, or drink offering accompanied the Passover observance recorded in Joshua 5, since no officially sanctioned altar yet existed. The same principle underscores the broader call to observe exactly what God commands without adding to or diminishing from His word.
