Charles Ellicott Commentary Psalms 118:5

"Out of my distress I called upon Jehovah: Jehovah answered me [and set me] in a large place." — Psalms 118:5 (ASV)

I called. —Better: out of the distress I cried to Jah; answered me, with freedom, Jah. The meaning of the last clause (literally, with room. Compare: “Ay, marry, now my soul has elbow-room”—King John) is determined by the parallelism of Psalm 18:19.

The versions read “freedom of Jah,” i.e., boundless freedom.
