1 Samuel 14:3-7

and Ahijah, the son of Ahitub, Ichabod’s brother, the son of Phinehas, the son of Eli, the priest of the Lord at Shiloh, was wearing an ephod. And the people did not know that Jonathan had gone.

Now between the gorges by which Jonathan sought to cross over to the Philistines’ garrison there was a rocky crag on the one side, and a rocky crag on the other side; and the name of the one was Bozez, and the name of the other, Seneh.

The one crag rose on the north opposite Michmash, and the other on the south opposite Geba.

Then Jonathan said to the young man who was carrying his armor, “Come, and let’s cross over to the garrison of these uncircumcised men; perhaps the Lord will work for us, because the Lord is not limited to saving by many or by few!”

His armor bearer said to him, “Do everything that is in your heart; turn yourself to it, and here I am with you, as your heart desires.”
