Deuteronomy 31:23

ויצו את יהושע בן נון AND HE COMMANDED JOSHUA THE SON OF NUN — This has to be connected with v. 14 above, and it refers to the Shechinah (to God; “He commanded” means “God commanded”), as it distinctly states here “[for thou shalt bring the children of Israel] into the land which “I” swore unto them, [and “I” will be with thee]”.

וַיְצַ֞ו אֶת־יְהוֹשֻׁ֣עַ בִּן־נ֗וּן וַיֹּ֘אמֶר֮ חֲזַ֣ק וֶאֱמָץ֒ כִּ֣י אַתָּ֗ה תָּבִיא֙ אֶת־בְּנֵ֣י יִשְׂרָאֵ֔ל אֶל־הָאָ֖רֶץ אֲשֶׁר־נִשְׁבַּ֣עְתִּי לָהֶ֑ם וְאָנֹכִ֖י אֶהְיֶ֥ה עִמָּֽךְ׃

And he gave Yehoshua the son of Nun a charge, and said, Be strong and of a good courage: for thou shalt bring the children of Yisra᾽el into the land of which I swore to them: and I will be with thee.
