Bastard
Easton's Dictionary
In the Old Testament the rendering of the Hebrew word mamzer’, which means “polluted.” In Deut. 23:2, it occurs in the ordinary sense of illegitimate offspring. In Zech. 9:6, the word is used in the sense of foreigner. From the history of Jephthah we learn that there were bastard offspring among the Jews (Judg. 11:1-7). In Heb. 12:8, the word (Gr. nothoi) is used in its ordinary sense, and denotes those who do not share the privileges of God’s children.
Smith's Dictionary
Among those who were excluded from entering the congregation, even to the tenth generation, was the bastard. (23:2) The term is not, however, applied to any illegitimate offspring, born out of wedlock, but is restricted by the rabbins to the issue of any connection within the degrees prohibited by the law.
