Jamieson, Fausset and Brown on Judges 14:3-4

3-4. Is there never a woman among the daughters of thy brethren--that is, "of thine own tribe"--a Danite woman.

Samson said ... Get her for me; for she pleaseth me well--literally, "she is right in mine eyes"; not by her beautiful countenance or handsome figure, but right or fit for his purpose. And this throws light on the historian's remark in reference to the resistance of his parents: they "knew not that it was of the Lord, that he sought an occasion against the Philistines"--rather, "from the Philistines"--originating on their side. The Lord, by a course of retributive proceedings, was about to destroy the Philistine power, and the means which He meant to employ was not the forces of a numerous army, as in the case of the preceding judges, but the miraculous prowess of the single-handed champion of Israel. In these circumstances, the provocation to hostilities could only spring out of a private quarrel, and this marriage scheme was doubtless suggested by the secret influence of the Spirit as the best way of accomplishing the intended result.
