Moreover the Hebrews that were with the Philistines before that time, which went up with them into the camp from the country round about, even they also turned to be with the Israelites that were with Saul and Jonathan. The Hebrews that were with the Philistines - We may understand such as they held in bondage, or who were their servants. Instead of Hebrews the Septuagint read, οἱ δουλοι, the slaves; from which it is evident that, instead of עברים Ibrim, Hebrews, they found in their text עבדים abadim, servants. But this reading is not countenanced by any other version, nor by any MS. yet discovered.
