In Joshua 8:1, God promises to give Ai into Joshua's hand; here he instructs the ambush to take possession, fulfilling that promise.

Joshua 8:2 is the command to set an ambush which this verse executes — same narrative context.

Joshua 8:18 continues the same battle plan with 'I have given it into your hand' — parallel divine promise.

Numbers 21:34 uses the same phrase 'I have given him into your hand' — a direct verbal parallel of divine assurance.
