ho'-resh (choreshah, 1 Samuel 23:15, 18, margin only; Septuagint en Te Kaine, "in the New"; English Versions of the Bible "in the wood" (ba-choreshdh), the particle "in" being combined with the article): Choresh in other passages is translated "forest" (compare 2 Chronicles 27:4 Isaiah 17:9 Ezekiel 31:3 ) and it is most probable that it should be so translated here.
