Note 29 — ON THE MORNING OF CHRIST'S NATIVITY.
Reading edition
Why are the Cherubim "helmed," while the Seraphim are "sworded"? Addison says, "Some of the rabbins tell us that the cherubims are a set of angels who know most, and the seraphims a set of angels who love most." Observe that the plural of cherub or of seraph may be formed in three ways: viz. cherubs, cherubim, cherubims; seraphs, seraphim, seraphims.
