Permit me to make a correction
the word atonement which wasnt "translated into English" until the 16th century
However, “kippur”(Strong's H3725, prim root H3722) is 1st revealed in YHVH’s Hebrew in Exodus 29 and further defined in Leviticus 23:26-32, the High Sabbath(convocation) of Yom-Kippur, the day appointed chosen by YHVH and set aside for the annual atonement for sins of the ecclesia by the High Priest. It is a permanent regulation that is to be observed forever.
The ENGLISH word wasn’t CREATED until the 16th century. Other words appear in the MSS prior. My comment stands.
