Charles Ellicott Commentary 1 Samuel 23:15

"And David saw that Saul was come out to seek his life: and David was in the wilderness of Ziph in the wood." — 1 Samuel 23:15 (ASV)

In a wood. —Some have understood this as a proper name, Horesh. There is no trace of the wood now. The land lost its ornament of trees centuries ago, through the desolating hand of man.— Van der Velde.
