For three things the earth trembles, under four it cannot bear up:
All Commentaries on Proverbs 30:21 Go To Proverbs 30
Hippolytus of Rome
AD 235
By three things the earth is moved,” viz., by the Father, the Son, and the Holy Ghost. “And the fourth it cannot bear,” viz., the last appearing of Christ. “When a servant reigneth:” Israel was a slave in Egypt, and in the land of promise became a ruler. “And a fool when he is filled with meat:” i.e., getting the land in possession readily, and eating its fruit, and being filled, it (the people) kicked. “And a handmaid when she casts out her mistress:” i.e., the synagogue which took the life of the Lord, and crucified the flesh of Christ.
