Albert Barnes on 1 Timothy 5:15

For some are already turned aside after Satan. That is, some young widows. The meaning is, that in the respects above mentioned, 1Timm 5:13, they had followed the great Tempter, rather than the Lord Jesus. This is stated as a reason why they should not be admitted into the number of the widows who were to be maintained at the expense of the church, and to whom the care of the younger female members was to be committed.
