until Yahweh has given your brothers rest, as he has given you, and they have also possessed the land which Yahweh your God gives them. Then you shall return to the land of your possession, and possess it, which Moses the servant of Yahweh gave you beyond the Jordan toward the sunrise.’”
Joshua 1:13 “Remember the word which Moses the servant of Yahweh commanded you, saying, ‘Yahweh your God gives you rest, and will give you this land.
Joshua 1:14 Your wives, your little ones, and your livestock, shall live in the land which Moses gave you beyond the Jordan; but you shall pass over before your brothers armed, all the mighty men of valor, and shall help them
Joshua 1:15 until Yahweh has given your brothers rest, as he has given you, and they have also possessed the land which Yahweh your God gives them. Then you shall return to the land of your possession, and possess it, which Moses the servant of Yahweh gave you beyond the Jordan toward the sunrise.’”
Joshua 1:16 They answered Joshua, saying, “All that you have commanded us we will do, and wherever you send us we will go.
Joshua 1:17 Just as we listened to Moses in all things, so will we listen to you. Only may Yahweh your God be with you, as he was with Moses.
The verse centers on "until", "yahweh", "given", "brothers", "rest", "possessed", and "land". It is saying that the verse draws attention to "until" and "yahweh", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "Your wives your little ones and your..." into verse 16's "They answered Joshua saying All that you...", so "until" and "yahweh" belong inside that flow. In Joshua context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "until" and "yahweh" with trust shaped by these words, not by a vague optimism outside the passage.
