Shaalabbin: Eusebius calls it Σαλαβα:, and places it in Samaria, and Jerome calls it Salebi (Ezekiel 48:1-35), and joins it to Ajalon and Emmaus. Judges 1:35, Shaalbim
Ajalon: This appears to be the Ajalon which Jerome places two miles from Nicopolis or Emmaus, in the road to Jerusalem. Joshua 10:12, Joshua 21:24; 1 Samuel 14:31
