Isaiah 27:12
And it shall come to pass in that day, that the LORD shall beat off from the channel of the river unto the stream of Egypt, and ye shall be gathered one by one, O ye children of Israel. And it shall come to pass in that day, that the LORD shall beat off from the channel of the river unto the stream of Egypt, and ye shall be gathered one by one, O ye children of Israel.
The Lord is shown gathering the children of Israel singly, taking them one by one. In the present this is fulfilled as the truth collects souls individually from separate places, one here and another there. Every person truly converted in this gathering becomes a means of extending the work still farther.
