How he went into the house of God] The place where the tabernacle and the ark was: for the temple was not yet built.
in the days of Abiathar] Called Ahimelech, 1 Samuel 21:1. and sometimes Abiathar. Compare 1 Chronicles 24:6. 2 Samuel 8:17. and 2 Samuel 15:29. 1 Kings 2:26. 2 Kings 25:18.
the high priest] He was of the house of Ithamar; but Eli, being elder then any of the house of Eleazar, kept the title in himself and his, till Solomon put out this Abiathar, 1 Samuel 2:31; 1 Samuel 2:35. 1 Kings 2:27. Or, it may be that Abiathar was present with his father Ahimelech, and is named, as better known, by his long priesthood.
and gave also to them which were with him?] To prevent an exense that might be brought from the dignity of Davids person.
