Deuteronomy 4:36 Meaning and Commentary

Deuteronomy 4:36

Out of heaven he made thee to hear his voice, that he might
instruct thee
Thunder is the voice of God, and by which he instructs men in the greatness of his power, ( Job 26:14 ) ( 40:9 ) ( Psalms 29:3 ) , &c. unless his voice in giving the law, which was for the instruction of Israel, is meant; for that was heard on earth, on Mount Sinai, to which the following refers:

and upon earth he showed thee his great fire;
on Mount Sinai, which burned with it:

and thou heardest his words out of the midst of the fire;
the ten commands, and therefore may well be called, a fiery law; see ( Deuteronomy 4:12 Deuteronomy 4:15 Deuteronomy 4:33 ) .

Deuteronomy 4:36 In-Context

34 if God has assayed to go and take to himself a nation out of the midst of nation with trial, and with signs, and with wonders, and with war, and with a mighty hand, and with a high arm, and with great sights, according to all the things which the Lord our God did in Egypt in thy sight.
35 So that thou shouldest know that the Lord thy God he is God, and there is none beside him.
36 His voice was made audible from heaven to instruct thee, and he shewed thee upon the earth his great fire, and thou heardest his words out of the midst of the fire.
37 Because he loved thy fathers, he also chose you their seed after them, and he brought thee himself with his great strength out of Egypt,
38 to destroy nations great and stronger than thou before thy face, to bring thee in, to give thee their land to inherit, as thou hast it this day.
