Charles Ellicott Commentary Psalms 29:6

"He maketh them also to skip like a calf; Lebanon and Sirion like a young wild-ox." — Psalms 29:6 (ASV)

Those trees that are not snapped off, bending to the storm, and swaying in the wind, seem to bound like wild buffaloes .

Sirion, according to Deuteronomy 3:9 (see this verse), was the Sidonian name of Hermon. Here, it refers to the whole range of Anti-Libanus.

Unicorn. —See Psalm 22:21, Note.

There is some ambiguity about the suffix, them. It may relate to the mountains instead of the cedars, and some commentators divide the clauses thus: “He makes them skip; like a calf Lebanon, and Sirion like a young buffalo.” It is not, however, necessary to suppose, with some, that an earthquake accompanies the storm; the apparent movement of the hills being introduced to heighten the effect of the violence of the tempest.
