Raise up a signal for the peoples.” (Isaiah 62:10) In the first instance, this call likely refers to passing out of the gates of the cities of Babylonia in order to return to Jerusalem. The returnees are to clear stones out of the way to make the journey easier and to raise up a signal to show the way.​—Isaiah 11:12.

21, 22. What signal has Jehovah established for those leaving false religion, and how do we know?

²¹ In 537 B.C.E., Jerusalem became the signal that beckoned the Jewish remnant to return and rebuild the temple. (Isaiah 49:22) In 1919 when the anointed remnant were delivered from bondage to false religion, they did not wander aimlessly. They knew their destination, for Jehovah had established a signal for them. What signal? The same signal foretold at Isaiah 11:10, which reads: “It must occur in that day that there will be the root of Jesse that will be standing up as a signal for the peoples.” The apostle Paul applies these words to Jesus. (Romans 15:8, 12) Yes, the signal is Christ Jesus, reigning as King on heavenly Mount Zion!​—Hebrews 12:22; Revelation 14:1.

²² Around Jesus Christ, both the anointed Christians and the other sheep are gathered to engage in the unifying worship of the Most High God. His rulership serves to vindicate Jehovah’s universal sovereignty and to bless honesthearted ones out of all nations of the earth. Is this not reason for every one of us to join in exalting him with praise?
