Hashem tells Moshe to take Yehoshua and place his hands upon his head [giving him "semicha"]. Then he should bring him in front of Elazar Hakohen and the nation and "pass the baton" of leadership.
וַיֹּ֨אמֶר יְהֹוָ֜ה אֶל־מֹשֶׁ֗ה קַח־לְךָ֙ אֶת־יְהוֹשֻׁ֣עַ בִּן־נ֔וּן אִ֖ישׁ אֲשֶׁר־ר֣וּחַ בּ֑וֹ וְסָמַכְתָּ֥ אֶת־יָדְךָ֖ עָלָֽיו:
וְהַֽעֲמַדְתָּ֣ אֹת֗וֹ לִפְנֵי֙ אֶלְעָזָ֣ר הַכֹּהֵ֔ן וְלִפְנֵ֖י כׇּל־הָעֵדָ֑ה וְצִוִּיתָ֥ה אֹת֖וֹ לְעֵינֵיהֶֽם׃
What does Moshe do? JUST the opposite!! First he stands him in front of Elazar and the people and only then places his hands on his head.
וַיַּ֣עַשׂ מֹשֶׁ֔ה כַּאֲשֶׁ֛ר צִוָּ֥ה יְהֹוָ֖ה אֹת֑וֹ וַיִּקַּ֣ח אֶת־יְהוֹשֻׁ֗עַ וַיַּֽעֲמִדֵ֙הוּ֙ לִפְנֵי֙ אֶלְעָזָ֣ר הַכֹּהֵ֔ן וְלִפְנֵ֖י כׇּל־הָעֵדָֽה׃
וַיִּסְמֹ֧ךְ אֶת־יָדָ֛יו עָלָ֖יו וַיְצַוֵּ֑הוּ כַּאֲשֶׁ֛ר דִּבֶּ֥ר יְהֹוָ֖ה בְּיַד־מֹשֶֽׁה׃
Why not do it Hashem's way??
