While he was sleeping from exhaustion, Heber’s wife Jael took a tent peg, grabbed a hammer, and went silently to Sisera. She hammered the peg into his temple and drove it into the ground, and he died.

The horses’ hooves then hammered—
the galloping, galloping of his stallions.

She reached for a tent peg,
her right hand, for a workman’s mallet.
Then she hammered Sisera—
she crushed his head;
she shattered and pierced his temple.
