Put I my trust. — Better, as in Psalms 7:1, I find my refuge.
Flee as a bird. — Literally, flee ye a bird. The plural verb, with the singular noun, offers a difficulty which is not obviated by the reading which changes the verb to the singular, since your mountain has the plural suffix.

The idea of trepidation is conveyed in the original by the verb, which suggests the hurried flap of wings. Dr. Thomson, in The Land and the Book, finds in the habits of the dove an illustration of the passage; and compares Psalms 55:6, “Oh that I had wings as a dove!”
