Sirach 50:28LXX

26That Israel may believe that the mercy of God is with us, to deliver us in his days.

27There are two nations which my soul abhorreth: and the third is no nation, which I hate:

28They that sit on mount Seir, and the Philistines, and the foolish people that dwell in Sichem.

29Jesus the son of Sirach, of Jerusalem, hath written in this book the doctrine of wisdom and instruction, who renewed wisdom from his heart.

30Blessed is he that is conversant in these good things: and he that layeth them up in his heart, shall be wise always.
