“Let not a widow be taken into the number under threescore years old, having been the wife of one man,”
King James Version (KJV)
5:9 Let not a widow be chosen - Into the number of deaconesses, who attended sick women or travelling preachers. Under threescore - Afterwards they were admitted at forty, if they were eminent for holiness. Having been the wife of one husband - That is, having lived in lawful marriage, whether with one or more persons successively.
1Ti 5:9 Let not a widow be taken into the number. Into the order of widows supported by the church and engaged in its work. Under three-score years old. None but the aged. Having been the wife of one man. Not having had more than one husband living at the same time, as was very common in those days of easy divorce.
