¹³ In Bible times it was the custom for women to celebrate victories, crying out or singing the good news of battles won or of coming relief. (1 Samuel 18:6, 7; Psalm 68:11) Isaiah prophetically indicates that there is good news for the Jewish exiles, news that can be fearlessly shouted, even from the mountaintops​—Jehovah will lead his people back to their beloved Jerusalem!

This is good news that must be fearlessly proclaimed, as if by shouting from the mountaintops so that the proclamation carries far and wide. Let us, then, lift up our voices and boldly let others know that Jehovah God has restored his pure worship on this earth!
