John Gill Bible Commentary

And while he yet spake, behold, Jonathan the son of Abiathar the priest came,.... Whom his father had left in the city, to observe what passed there, and give him notice of it: and Adonijah said unto him, come in, for thou art a valiant man, and bringest good tidings; which seems to be not a very wise speech, as if there was a connection between being valiant, and bringing good news, or that the one had any influence upon the other; though perhaps it means no more than a good man, "a man of virtue" (i), as it may be rendered; one that fears sin, as the Targum, and so would report nothing but what was true, and therefore might be depended on; see Sa2 18:27; the same phrase is rendered "a worthy man", Kg1 1:52. (i) "vir virtutis", Montanus, Vatablus.
