Verse 20. "But Samson's wife was given to his companion" - This was the same kind of person who is called the friend of the bridegroom, John iii. 29.
And it is very likely that she loved this person better than she loved her husband, and went to him as soon as Samson had gone to his father's house at Zorah. She might, however, have thought herself abandoned by him, and therefore took another; this appears to have been the persuasion of her father, chap. xv. 2. But her betraying his secret and his interests to his enemies was a full proof he was not very dear to her; though, to persuade him to the contrary, she shed many crocodile tears; see ver. 16. He could not keep his own secret, and he was fool enough to suppose that another would be more faithful to him than he was to himself. Multitudes complain of the treachery of friends betraying their secrets, &c., never considering that they themselves have been their first betrayers, in confiding to others what they pretend to wish should be a secret to the whole world! If a man never let his secret out of his own bosom, it is impossible that he should ever be betrayed.
