Adam Clarke on 1 Samuel 13:3

Jonathan smote - He appears to have taken this garrison by surprise, for his men had no arms for a regular battle, or taking the place by storm. This is the first place in which this brave and excellent man appears; a man who bears one of the most amiable characters in the Bible.

Let the Hebrews hear - Probably this means the people who dwelt beyond Jordan, who might very naturally be termed here העברים haibrim, from עבר abar, he passed over; those who are beyond the river Jordan: as Abraham was called עברי Ibri because he dwelt beyond the river Euphrates.
