Or HaChaim on Genesis 49:16/אור החיים על בראשית מ״ט:ט״ז

1 דן ידין עמו, "Dan will judge his people, etc.". Jacob may have wanted to exonerate Samson who had disgraced himself as a leader by consorting with Delilah. Perhaps Jacob considered Samson's end when he asked G'd to die together with the Philistines (Judges 16,30) he was about to kill as a redeeming conclusion of his life; this is why he compared him כאחד שבטי ישראל, like the unique personalities each of the tribes produced at one time or another.
