Don’t be intimidated by these two stubs of smoking logs, or by the raging anger of Rezin, Syria, and the son of Remaliah. 7:5 Syria has plotted with Ephraim and the son of Remaliah to bring about your demise. 7:6 They say, “Let’s attack Judah, terrorize it, and conquer it. Then we’ll set up the son of Tabeel as its king.”
