Synagogues are buildings used for assembly, worship, and preaching. Alma and Amulek preached in synagogues “which were built after the manner of the Jews” (Alma 16:13). In the land of Ishmael, the king caused synagogues to be built and caused the people under his reign to assemble together (Alma 21:20).
Aaron preached to the Amalekites in synagogues they had built “after the order of the Nehors” (Alma 21:4). When Aaron entered one synagogue to preach, an Amalekite contended with him and asked, “Hast thou seen an angel” (Alma 21:5)?. Speakers who entered temples and synagogues to teach were cast out, mocked, smitten, stoned, bound, and imprisoned (Alma 26:29).
The Zoramites built synagogues and gathered on one day of the week, “which day they did call the day of the Lord” (Alma 31:12). Poor people were cast out of the synagogues because of “the coarseness of their apparel” and were not permitted to enter to worship God (Alma 32:2; Alma 32:3). Jesus commanded, “ye shall not cast him out of your synagogues, or your places of worship” (3 Nephi 18:32).
