וְיָרְד֣וּ כָל־עֲבָדֶיךָ֩ אֵ֨לֶּה אֵלַ֜י וְהִשְׁתַּֽחֲוּוּ־לִ֣י לֵאמֹ֗ר צֵ֤א אַתָּה֙ וְכָל־הָעָ֣ם אֲשֶׁר־בְּרַגְלֶ֔יךָ וְאַחֲרֵי־כֵ֖ן אֵצֵ֑א וַיֵּצֵ֥א מֵֽעִם־פַּרְעֹ֖ה בָּחֳרִי־אָֽף׃ (ס)
你這些臣僕都要下來見我，向我下拜，說：『你和所有跟隨你的百姓都出去吧！』此後我才出去。」他就怒氣沖沖地從法老那裡出去了。

THE term regel is homonymous, signifying, in the first place, the foot of a living being; comp. “Foot for foot” (Exod. 21:24). Next it denotes an object which follows another: comp. “And all the people that follow thee” (lit. that are at thy feet) (ib. 11:8). Another signification of the word is “cause”; comp. “And the Lord hath blessed thee, I being the cause” (leragli) (Gen. 30:30), i.e., for my sake; for that which exists for the sake of another thing has the latter for its final cause. Examples of the term used in this sense are numerous. It has that meaning in Genesis 33:14, “Because (leregel) of the cattle that goeth before me, and because (leregel) of the children.”
