“you.” The “you” verb is singular. See commentary on Exodus 20:3, “you.”
“in the land.” That is, in the land of Israel. Israel, the “Promised Land,” was the land God was giving to the Israelites.
“is giving you.” Some versions have “is about to give you,” and the Hebrew can have that meaning, and also that was mostly true since Israel had not crossed the Jordan River yet, but by Deuteronomy the process of God giving the Promised Land to Israel had begun. For one thing, the Canaanites had heard that Israel was coming and were afraid of them, which gave Israel an advantage (Josh. 2:9).
