puis il fondit sur le Philistin, lui prit son épée qu’il tira du fourreau, et le tua en lui tranchant la tête. Les Philistins, voyant que leur champion était mort, prirent la fuite.
Radak
When my enemies turn back, They stumble and perish at Thy presence. – For all the Philistine armies fled and turned back, as it is written (1 Sam. 17:51): “And when the Philistines saw that their champion was dead they fled.”
Rashi
