The Lord in the past gathered his people geographically through creating places where Saints came together and established the Church. Today we gather throughout the world in local congregations, we gather spiritually through covenants, and we gather virtually as a whole church for general conferences.
Find on this web page “Weeks 10-16: The First Year (1830, D&C 20-40),” “Leaving New York.” This map shows how members of the fledgling church moved in groups from New York to Ohio in spring 1831, fulfilling the command given in D&C 37. First the families in Colesville (such as the Knights) gathered in Ithaca and then traveled north by boat on Cayuga Lake. They rode barges down the Cayuga and Seneca Canal and then the Erie Canal to Buffalo. They went by boat on Lake Erie to Fairport Harbor and overland to Kirtland, Ohio. The Fayette branch (including the Whitmer family) and the Manchester-Palmyra branch followed soon afterward along the same travel lines.

For Latter-day Saints, the gathering of Israel involves bringing together the heirs of the covenant to designated places where they can enjoy the blessings of temples.
