וַיָּשֻׁ֙בוּ֙ בְּנֵ֣י יִשְׂרָאֵ֔ל מִדְּלֹ֖ק אַחֲרֵ֣י פְלִשְׁתִּ֑ים וַיָּשֹׁ֖סּוּ אֶת־מַחֲנֵיהֶֽם׃
And the children of Israel returned from chasing after the Philistines, and they spoiled their camp.
Rashi
דלקת means THOU HAST PURSUED — as in (Lamentations 4:19) “They chased us (דלקנו) upon the mountains”, and (1 Samuel 17:53) ‘‘from chasing (מדלק) after the Philistines”.
