Numbers 13:2

שלח לך אנשים SEND THOU MEN — Why is the section dealing with the spies put in juxtaposition with the section dealing with Miriam’s punishment? To show the grievousness of the spies’ sin: because she (Miriam) was punished on account of the slander which she uttered against her brother, and these sinners witnessed it and yet they did not take a lesson from her (Midrash Tanchuma, Sh'lach 5). שלח לך SEND THEE (more lit., for thyself) — i.e. according to your own judgement: I do not command you, but if you wish to do so send them. — God said this because the Israelites came to Moses and said. “We will send men before us etc.”, as it is said, (Deuteronomy 1:22): “And you approached me, all of you, [saying, We will send men, etc.]”, and Moses took counsel with the Shechinah (the Lord), whereupon He said to them, I have told them long ago that it (the land) is good, as it is said, (Exodus 3:17): “I will bring you up out of the affliction of Egypt … [unto a land flowing with milk and honey]”. By their lives! I swear that I will give them now an opportunity to fall into error through the statements of the spies, so that they should not come into possession of it (the land) (Sotah 34b; cf. also Rashi on Sotah 34b:8 מדעתך and Midrash Tanchuma, Sh'lach 5).

שְׁלַח־לְךָ֣ אֲנָשִׁ֗ים וְיָתֻ֙רוּ֙ אֶת־אֶ֣רֶץ כְּנַ֔עַן אֲשֶׁר־אֲנִ֥י נֹתֵ֖ן לִבְנֵ֣י יִשְׂרָאֵ֑ל אִ֣ישׁ אֶחָד֩ אִ֨ישׁ אֶחָ֜ד לְמַטֵּ֤ה אֲבֹתָיו֙ תִּשְׁלָ֔חוּ כֹּ֖ל נָשִׂ֥יא בָהֶֽם׃

Send thou men, that they may spy out the land of Kena῾an, which I give to the children of Yisra᾽el: of every tribe of their fathers shall you send a man, every one a ruler among them.
