John Gill Commentary Judges 4:22

"And, behold, as Barak pursued Sisera, Jael came out to meet him, and said unto him, Come, and I will show thee the man whom thou seekest. And he came unto her; and, behold, Sisera lay dead, and the tent-pin was in his temples." — Judges 4:22 (ASV)

And, behold, as Barak pursued Sisera Knowing the way he took, at least as he supposed:

Jael came out to meet him ; as she did Sisera, but with greater pleasure:

and said unto him, come, and I will show thee the man whom thou seekest ; for she full well knew whom he was in pursuit of:

and when he came into her [tent] ; at her invitation:

behold, Sisera lay dead, and the nail [was] in his temples : which she did not attempt to draw out, but left it there, that it might be seen in what way she had dispatched him.
