What Does Exodus 8:27 Mean?

"We must go three days' journey into the wilderness and sacrifice to the LORD our God as he tells us." Moses restates the original demand in verse 27: it is not negotiable. "We must go" (Hebrew: derech sheloshet yamim nelech bamidbar, literally "a three-day journey we will go in the wilderness") is the same formulation Moses used when approaching Pharaoh in chapter 5.

The specificity of "three days' journey" is repeated unchanged: the location (wilderness), the distance (three days), and the destination (sacrifice to YHWH) are all maintained as non-negotiable. Moses does not meet Pharaoh's counter-offer with a counter-counter-offer; he restates the original demand.

The closing phrase "as he tells us" (Hebrew: ka'Asher yomar elenu, "as he will say to us") is a forward-pointing divine authority claim: Moses and Aaron will do what YHWH tells them to do at the place of sacrifice, and that cannot be determined in advance by Pharaoh's conditions.

The form of worship "as he tells us" acknowledges that the specific content and mode of the wilderness worship has not yet been fully revealed to Moses either: what is being insisted on is the obedience-framework, not a detailed liturgical plan. Israel will worship YHWH in the wilderness according to YHWH's instruction, which is not available for Pharaoh's pre-approval or modification.

The "as he tells us" element of verse 27 prefigures the Sinai revelation: the wilderness journey that begins with the three-day worship request will culminate in the massive divine self-disclosure at Sinai where YHWH will indeed tell Israel exactly how to worship him through the tabernacle system, the priesthood, and the sacrificial calendar. The forward-pointing "as he tells us" is, from the perspective of the canonical narrative, a prophecy of everything from Sinai to Leviticus: the form of worship will be divinely specified in the wilderness to which Pharaoh is being asked to let Israel go.
