1 Samuel 21:1-9

Introduction

David comes to Ahimelech at Nob, receives provisions from him, and the sword of Goliath; and is noticed by Doeg, one of the servants of Saul, 1Sam 21:1-9. He leaves Nob, and goes to Achish, king of Gath, 1Sam 21:10. But on being recognised as the vanquisher of Goliath by the servants of Achish, he feigns himself deranged, and Achish sends him away, 1Sam 21:11-15.

Verse 1

Then came David to Nob - There were two places of this name, one on this side, the second on the other side of Jordan; but it is generally supposed that Nob, near Gibeah of Benjamin, is the place here intended; it was about twelve miles from Jerusalem.

Why art thou alone - Ahimelech probably knew nothing of the difference between Saul and David; and as he knew him to be the king's son-in-law, he wondered to see him come without any attendants.
Verse 2

The king hath commanded me a business - All said here is an untruth, and could not be dictated by the Spirit of the Lord; but there is no reason to believe that David was under the influence of Divine inspiration at this time. It is well known that from all antiquity it was held no crime to tell a lie, in order to save life. Thus Diphilus: - Ὑπολαμβανω το ψευδος επι σωτηριᾳ Λεγομενον, ουδεν περιποιεισθαι δυσχερες. "I hold it right to tell a lie, in order to procure my personal safety; nothing should be avoided in order to save life."

A heathen may say or sing thus; but no Christian can act thus, and save his soul, though he by doing so may save his life.
Verse 6

So the priest gave him hallowed bread - To this history our Lord alludes, Mar 2:25, in order to show that in cases of absolute necessity a breach of the ritual law was no sin. It was lawful for the priests only to eat the shew-bread; but David and his companions were starving, no other bread could be had at the time, and therefore he and his companions ate of it without sin.
Verse 7

Detained before the Lord - Probably fulfilling some vow to the Lord, and therefore for a time resident at the tabernacle.

And his name was Doeg - From 1Sam 22:9 we learn that this man betrayed David's secret to Saul, which caused him to destroy the city, and slay eighty-five priests. We learn from its title that the fifty-second Psalm was made on this occasion; but titles are not to be implicitly trusted.
Verse 9

The sword of Goliath - It has already been conjectured (see 1 Samuel 17:1-58) that the sword of Goliath was laid up as a trophy in the tabernacle.
