Then Moses called to Joshua and said to him in the sight of all Israel, “Be strong and courageous, for you shall go with this people into the land which Yahweh has sworn to their fathers to give them, and you shall give it to them as an inheritance.
Deuteronomy 31:5 And Yahweh will give them over before you, and you shall do to them according to all the commandments which I have commanded you.
Deuteronomy 31:6 Be strong and courageous. Do not be afraid or be in dread of them, for Yahweh your God is the one who goes with you. He will not fail you or forsake you.”
Deuteronomy 31:7 Then Moses called to Joshua and said to him in the sight of all Israel, “Be strong and courageous, for you shall go with this people into the land which Yahweh has sworn to their fathers to give them, and you shall give it to them as an inheritance.
Deuteronomy 31:8 And Yahweh is the one who goes ahead of you; He will be with you. He will not fail you or forsake you. Do not fear or be dismayed.”
Deuteronomy 31:9 So Moses wrote this law and gave it to the priests, the sons of Levi who carried the ark of the covenant of Yahweh, and to all the elders of Israel.
The verse centers on "called", "moses", "joshua", "said", "sight", "israel", "strong", and "courageous". It is saying that the verse draws attention to "called" and "moses", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "Be strong and courageous Do not be..." into verse 8's "And Yahweh is the one who goes...", so "called" and "moses" belong inside that flow. In Deuteronomy context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "called" and "moses" with trust shaped by these words, not by a vague optimism outside the passage.
