KJV:
She put her hand to the nail, and her right hand to the workmen's hammer; and with the hammer she smote Sisera, she smote off his head, when she had pierced and stricken through his temples.
NASB:
"She reached out her hand for the tent peg, And her right hand for the workmen's hammer. Then she struck Sisera, she smashed his head; And she shattered and pierced his temple.
