Because you trespassed against me in the midst of the children of Israel, at the waters of contradiction, in Cades of the desert of Sin: and you did not sanctify me among the children of Israel.
עַל֩ אֲשֶׁ֨ר מְעַלְתֶּ֜ם בִּ֗י בְּתוֹךְ֙ בְּנֵ֣י יִשְׂרָאֵ֔ל בְּמֵֽי־מְרִיבַ֥ת קָדֵ֖שׁ מִדְבַּר־צִ֑ן עַ֣ל אֲשֶׁ֤ר לֹֽא־קִדַּשְׁתֶּם֙ אוֹתִ֔י בְּת֖וֹךְ בְּנֵ֥י יִשְׂרָאֵֽל׃
One Church Father comments on this verse
Moses indeed struck the rock with his staff, filled with uncertainty (See Num. 20:1-13), thereby setting this miracle apart from others where his faith was firm. In this instance, he acted and was met with the revelation that he must cease his journey and would not enter the promised land. Overwhelmed by the complaints of a faithless people, he failed to maintain the faith he should have upheld.
