“wait for me.” We must wait for God. His promises sometimes seem delayed, but they will come. Many people think and act like there will not be a Day of Judgment, but there will be. We must be patient and faithful. God does not lie, and He tells us to wait for His judgment.
“I rise up to testify.” At the time of the End, God will testify against humanity. God’s court will be seated and judgment will take place (Dan. 7:9-10; Rev. 4:2-5). The Hebrew text, if the vowels are added differently, can read “rise up for the prey,” but although the Massoretic Hebrew Text reads that way, it seems less likely. For example, the Septuagint reads “for a witness.”
“for in the fire of my jealousy all the earth will be devoured.” Although much destruction would occur to Israel and the nations between 600 BC and the Day of Yahweh (which is still future), this prophecy is for more than those short and local destructions. In the Day of God’s wrath, the Tribulation and Armageddon, all the earth will be devoured. Indescribable devastation is foretold for the earth during that time (see commentary on Daniel 12:1).
