(Bamidbar 31:6) "And Moses sent them, a thousand to a tribe to the host, them and Pinchas": We are hereby apprised that they were as "weighty" as Pinchas, and Pinchas was over and against all of them. Why did Pinchas go and not Elazar? Because Pinchas went to take revenge (of the Midianites) for his mother's father (Yithro, viz. Shemot 2:16), it being written (Bereshit 37:36) "And the Midianites sold him (Joseph) to Egypt." (Bamidbar, Ibid.) "and the holy articles … in his hand": This refers to the ark, viz. (Ibid. 4:20) "And they shall not see when the 'holy' is being covered, lest they die." (Ibid. 31:6) "in his hand": "his hand" is his domain, as in (Ibid. 21:26) "and he took all his land from his hand," and (Bereshit 24:10) "and all the good of his master in his hand."
