Charles Ellicott Commentary Psalms 12:1

"Help, Jehovah; for the godly man ceaseth; For the faithful fail from among the children of men." — Psalms 12:1 (ASV)

Ceases. —Intransitive, as in Psalms 7:9.

The faithful. —The Vulgate and Syriac treat this word as abstract: “truth,” “faithfulness.” So Ewald; but the parallelism here, as in Psalms 31:23, requires it in the concrete. (Compare to 2 Samuel 20:19.) The Hebrew is cognate with “amen,” and Luther has “amen’s leute,” people as good as their word.
