Charles Ellicott Commentary Psalms 18:29

"For by thee I run upon a troop; And by my God do I leap over a wall." — Psalms 18:29 (ASV)

Better with the verbs in the present—
“For by you I scatter a troop,
By you I scale walls.”

A graphic reminiscence of warlike exploits. Some, however, read from Samuel “break down,” instead of “leap over.”
