What did the disciples understand by the phrase "gathered together unto My Name"?

What did the disciples understand by the phrase "gathered together unto My Name" (Matthew 18:20)?

The disciples did not lack acquaintance with the Old Testament. Their minds may have gone to the promise regarding Israel's future kingdom in Jeremiah 3:17, "At that time they shall call Jerusalem the throne of the Lord; and all the nations shall be gathered unto it, to the name of the Lord, to Jerusalem." This is reminiscent of the Lord's words to Israel when they came to the promised land, "Unto the place which the Lord your God shall choose . . . to put His name there, even unto His habitation . . . thither ye shall bring your burnt offerings" (Deuteronomy 12:5, 6). The Lord's name testifies to who He is.

It's reasonable to assume that the disciples understood that the place of public worship and of God's dwelling was now to be place of public testimony of which the Lord Jesus was the subject.
