1 Samuel 30:6

6. The people spake of stoning him They may have thought at first that David’s readiness to go to the war with Achish was unwise, and now as they felt their loss, they blamed him as the cause of all, and in the emotion of the hour were ready to mutiny. This was not strange when we consider the antecedents of many of these men. See 1 Samuel 22:2.

David encouraged himself in the Lord Betook himself to prayer, and through the ephod of the priest, as narrated in the following verses, received counsel and promise from Jehovah. Happy he, who in the hour of trouble knows how to encourage himself in Jehovah, for such a man shall surely triumph over all foes.
