Exodus 15:21

15:21 Miriam sang in response ¹  to them, “Sing to the Lord, for he has triumphed gloriously; the horse and its rider he has thrown into the sea.” ² 

Exodus 19:19

19:19 When the sound of the horn grew louder and louder, ³  Moses was speaking ⁴  and God was answering him with a voice. ⁵ 

[15:21]  ¹ tn The verb עָנָה (’ana) normally means “to answer,” but it can be used more technically to describe antiphonal singing in Hebrew and in Ugaritic.

[15:21]  ² sn This song of the sea is, then, a great song of praise for Yahweh’s deliverance of Israel at the Sea, and his preparation to lead them to the promised land, much to the (anticipated) dread of the nations. The principle here, and elsewhere in Scripture, is that the people of God naturally respond to God in praise for his great acts of deliverance. Few will match the powerful acts that were exhibited in Egypt, but these nonetheless set the tone. The song is certainly typological of the song of the saints in heaven who praise God for delivering them from the bondage of this world by judging the world. The focus of the praise, though, still is on the person (attributes) and works of God.

[19:19]  ³ tn The active participle הוֹלֵךְ (holekh) is used to add the idea of “continually” to the action of the sentence; here the trumpet became very loud – continually. See GKC 344 §113.u.

[19:19]  ⁴ tn The two verbs here (“spoke” and “answered”) are imperfect tenses; they emphasize repeated action but in past time. The customary imperfect usually is translated “would” or “used to” do the action, but here continuous action in past time is meant. S. R. Driver translates it “kept speaking” and “kept answering” (Exodus, 172).

[19:19]  ⁵ tn The text simply has בְּקוֹל (bÿqol); it could mean “with a voice” or it could mean “in thunder” since “voice” was used in v. 16 for thunder. In this context it would be natural to say that the repeated thunderings were the voice of God – but how is that an answer? Deut 4:12 says that the people heard the sound of words. U. Cassuto (Exodus, 232-33) rightly comments, “He was answering him with a loud voice so that it was possible for Moses to hear His words clearly in the midst of the storm.” He then draws a parallel from Ugaritic where it tells that one of the gods was speaking in a loud voice.
