Judges 5:5

5. Mountains quaked The fearful peals of thunder which accompanied the storm shook hills and plains. The English version, melted, (margin, flowed,) is after the Vulgate, and is supported by many interpreters, but is less suitable than quaked, which is the version of the Septuagint, Gesenius, Furst, and many of the best scholars. These latter derive the word from זלל , to shake, (compare Isaiah 64:1; Isaiah 64:3;) the former from נזל , to flow.

That Sinai The traditional seat of Jehovah, so famous in the history of the Hebrews. Sinai would naturally be mentioned if this storm came from the fields of Edom; for before Zion became the central seat of worship for all the tribes, Israel would naturally conceive of Jehovah as dwelling on Mount Sinai. So in this highly wrought description, that Sinai is represented as trembling when Jehovah moves from it northward to defend his people. Psalms 68:7-8, is evidently based on this passage in Judges, and is an imitation of it; but is so changed and modified as to suit its own particular context.
