baptismos denotes washings of objects and ceremonies, and baptism connected with burial, raising, and instruction.

The attested uses divide evenly between plural washings connected with vessels and ceremonial regulations, and baptismal language: burial and raising in Colossians 2:12 and instruction about baptisms in Hebrews 6:2.

1. Washings of vessels and ceremonial regulations · common

   In Mark 7:4, the accusative plural occurs in the clause concerning cups, pitchers, kettles, and beds; the APB renders these as “baptisms of cups and of pitchers and of kettles and of beds.” In Hebrews 9:10, the dative plural is included among food, drink, and external regulations, where the APB renders “various ceremonial washings.”

   Mark 7:4Hebrews 9:10
2. Baptism in instruction and burial-raising language · common

   In Colossians 2:12, the dative singular occurs in the statement of being buried and raised with him; the APB renders “buried with him in baptism.” In Hebrews 6:2, the genitive plural appears as the subject matter of instruction, rendered by the APB as “instruction about baptisms.”

   Colossians 2:12Hebrews 6:2

In the Anselm Project Bible: The APB renders the term with “baptism” and “baptisms” in Colossians 2:12 and Hebrews 6:2, but with “ceremonial washings” in Hebrews 9:10; Mark 7:4 uses “baptisms” for the washing of listed objects. These are verse-level renderings rather than definitions.
