1 Samuel 21:1
21:1a David went to Nob [located near Jerusalem (cf. Isa. 10:32); site of a large contingent of priests (cf. 1 Sam. 22:18)], to Ahimelech [a great grandson of Eli, the priest (14:3); name means “my brother is king”] the priest. Ahimelech trembled when he met him, and asked, “Why are you alone? Why is no one with you?”

1 Samuel 21:10
21:10 That day David fled from Saul and went to Achish king of Gath [major Philistine city and birthplace of Goliath (17:4); located 23 miles from Nob; perhaps David thought Saul would not consider looking for him in Gath].
