Charles Ellicott Commentary Psalms 57:1

"Be merciful unto me, O God, be merciful unto me; For my soul taketh refuge in thee: Yea, in the shadow of thy wings will I take refuge, Until [these] calamities be overpast." — Psalms 57:1 (ASV)

Trusts. — Better, has taken refuge. The future tense of the same verb occurs in the next clause.

Shadow of your wings. — See Note, Psalms 17:8.

Until these calamities. — Danger of destruction gives the feeling of the Hebrew better than “calamities.”
