Reference for Numbers 4:41

אֵ֣לֶּה פְקוּדֵ֗י מִשְׁפְּחֹת֙ בְּנֵ֣י גֵרְשׁ֔וֹן כָּל־הָעֹבֵ֖ד בְּאֹ֣הֶל מוֹעֵ֑ד אֲשֶׁ֨ר פָּקַ֥ד מֹשֶׁ֛ה וְאַהֲרֹ֖ן עַל־פִּ֥י יְהוָֽה׃

These are they that were numbered of the families of the sons of Gershon, of all that did serve in the tent of meeting, whom Moses and Aaron numbered according to the commandment of the LORD.
