To gender means to bring forth, beget, produce, or cause something to arise. It may refer to birth, the breeding of animals, or the production of strife and bondage.
The Bible uses the word for the birth of frost, the breeding of cattle, and the production of strife. In Galatians, Sinai is described as bearing children unto bondage, while Timothy is warned against disputes that gender strifes.
“Gender” is an older abbreviation of “engender.” Revised translations often use “give birth,” “bear,” or “beget,” according to the context.
