It happened, when Abiathar the son of Ahimelech fled to David to Keilah, that he came down with an ephod in his hand.
"Abiathar the son of Ahimelech ... came (to David) with an ephod in his hand"  (1 Samuel 23:6).  Scholars disagree as to the point in time when Abiathar came to David.  Willis placed their coming together here at Keilah.[4]  Matthew Henry's commentary supports Willis in this understanding of the passage;[5] however, Keil wrote that, "The words `to David to Keilah' are not to be understood as signifying that Abiathar did not come to David until he was in Keilah.  What is meant is that, `when he fled after David  (1 Samuel 22:20), he met with him as he was already preparing to march to the aid of Keilah and proceeded with David to Keilah.'"[6]  Of course, the International Critical Commentary would place  1 Samuel 23:6 at some other place in the narrative.[7]  This writer fails to see how the solution of this question involves anything very important.
