Keluaran 4:12

4:12 So now go, and I will be with your mouth ¹  and will teach you ²  what you must say.” ³ 

Yesaya 59:21

59:21 “As for me, this is my promise to ⁴  them,” says the Lord. “My spirit, who is upon you, and my words, which I have placed in your mouth, will not depart from your mouth or from the mouths of your children and descendants from this time forward,” ⁵  says the Lord.

[4:12]  ¹ sn The promise of divine presence always indicates intervention (for blessing or cursing). Here it means that God would be working through the organs of speech to help Moses speak. See Deut 18:18; Jer 1:9.

[4:12]  ² sn The verb is וְהוֹרֵיתִיךָ (vÿhoretikha), the Hiphil perfect with a vav (ו) consecutive. The form carries the instructional meaning because it follows the imperative “go.” In fact, there is a sequence at work here: “go…and/that I may teach you.” It is from יָרָה (yara), the same root behind תּוֹרָה (torah, “law”). This always referred to teaching either wisdom or revelation. Here Yahweh promises to teach Moses what to say.

[4:12]  ³ tn The form is the imperfect tense. While it could be taken as a future (“what you will say”), an obligatory imperfect captures the significance better (“what you must say” or “what you are to say”). Not even the content of the message will be left up to Moses.

[59:21]  ⁴ tn Or “my covenant with” (so many English versions); NCV “my agreement with.”

[59:21]  sn The Lord promises the repentant (note “to them”) that they and their offspring will possess his spirit and function as his spokesmen. In this regard they follow in the footsteps of the Lord’s special servant. See 42:1; 49:2; 51:16.

[59:21]  ⁵ tn Heb “from now and on into the future.”
