C. F. Keil and Franz Delitzsch on Judges 16:28

Jdg 16:28

Then Samson prayed to Jehovah, “Lord Jehovah, remember me, and only this time make me strong. O God, that I may avenge myself (with) the revenge of one of my two eyes upon the Philistines,” i.e., may take vengeance upon them for the loss of only one of my two eyes (משּׁתי, without Dagesh lene in the ת: see Ewald, §267, b.), - a sentence which shows how painfully he felt the loss of his two eyes, “a loss the severity of which even the terrible vengeance which he was meditating could never outweigh” (Bertheau).
