Jael went out to meet Sisera - He preferred the woman's tent because of secrecy; for, according to the etiquette of the eastern countries, no person ever intrudes into the apartments of the women. And in every dwelling the women have a separate apartment.

And Jael went out to meet Sisera,.... Seeing him coming, and knowing him full well, she stepped forward towards him, to invite him into her tent: some think she was looking out, that if she saw Israelite in distress to take him in; and very probably had been some time at her tent door, to inquire the battle went, and which, no doubt, living so near Kedesh, she knew was expected:
and said unto him, turn in, my lord; that is, into her tent: and she addresses him with the title of "lord", for the sake of honour, having been general of a large army; and not because her husband was a servant, and in subjection to him, as Abarbinel suggests:

she covered him with a mantle; either to hide him, should any search be made for him, or it may be to keep him from catching cold, being in a sweat through his flight, and being also perhaps inclined to sleep through weariness. The word for a mantle, according to Kimchi, signifies such a garment which has locks of wool on both sides of it, a sort of rug, and so very fit to cover with, and keep warm. So David de Pomis (m) describes it, as having locks and threads hanging down here and there.
(m) Tzemaeh David, fol. 216. 3.

Jael received the fugitive into her tent in the usual form of oriental hospitality (סוּר, as in Genesis 19:2-3, to turn aside from the road and approach a person), and covered him with a covering (שׂמיכה, ἁπ. λεγ., covering, or rug), that he might be able to sleep, as he was thoroughly exhausted with his flight.

Fear not - This was a promise of security, and therefore she cannot be excused from dissimulation and treachery.
