occurs only Eph. 5:19 and Col. 3:16. The verb to "sing an hymn"
occurs Matt. 26:30 and Mark 14:26. The same Greek word is
rendered to "sing praises" Acts 16:25 (R.V., "sing hymns") and
Heb. 2:12. The "hymn" which our Lord sang with his disciples at
the last Supper is generally supposed to have been the latter
part of the Hallel, comprehending Ps. 113-118. It was thus a
name given to a number of psalms taken together and forming a
devotional exercise.

The noun hymn is used only with reference to the services of
the Greeks, and was distinguished from the psalm. The Greek
tunes required Greek hymns. Our information regarding the
hymnology of the early Christians is very limited.
