מדרש על במדבר 27:22

(Bamidbar 27:22) "And Moses did as the L-rd commanded him": He did so with joy, undiluted with regret for his son and his brother's sons (i.e., for the honor not having been accorded them.) "and he 'took' Joshua": He "took" him with words, apprising him of the reward of the leaders of Israel in the world to come.
