אֶת־יְהוָ֧ה אֱלֹהֶ֛יךָ תִּירָ֖א וְאֹת֣וֹ תַעֲבֹ֑ד וּבִשְׁמ֖וֹ תִּשָּׁבֵֽעַ׃
C’est l’Éternel, ton Dieu, que tu dois adorer, c’est lui que tu dois servir, c’est par son nom que tu dois jurer.
Allegorical Interpretation of Genesis
[208] Moses too, let us observe, filled with wonder at the transcendency of the Uncreate, says, “and thou shalt swear by His Name” (Deut. 6:13), not “by Him,” for it is enough for the created being that he should be accredited and have witness borne to him by the Divine word: but let God be His own most sure guarantee and evidence.
