nD. The Old Testament writers claimed to be speaking the word of God. The expression “thus saith the Lord”, or its equivalent, occurs more than 2,000 times in the Old Testament (cf. 2 Sam. 23:1-2; Mt. 22:43; Isa. 1:1-2; Jer. 10:1-2; Ezek. 1:3). nE. Zechariah 7:12 mentions the complete process of revelation. The Lord sent His words by the Spirit through the prophets.
