[Hebrews 11:6]

Don’t forget the 300 concubines....

[daniel1212]

However, a concubine is a wife, if usually as a secondary one: (Gn. 25:1; cf. 1Ch. 1:32; Gn. 30:4; cf. Gn. 35:22; 2Sam. 16:21, 22, cf. 2Sam. 20:3)

And to be cut off from sex from their husband is to be a widow.

And David came to his house at Jerusalem; and the king took the ten women his concubines, whom he had left to keep the house, and put them in ward, and fed them, but went not in unto them. So they were shut up unto the day of their death, living in widowhood.  2 Sam. 20:3
