Jael went out to meet Sisera, and said to him, Turn in, my lord, turn in to me; don't be afraid. He came in to her into the tent, and she covered him with a rug.
Note the vulnerability and dependence of Sisera in Judges 4:19 and his blind self-confidence in Judges 4:20. He thought he was safe and in control, but he was in mortal danger, about to die, and he did not even suspect it. Such is often the case with people, especially the enemies of God’s people (cf. Proverbs 16:18).
