Jamieson, Fausset and Brown on 1 Corinthians 14:17

17. givest thanks--The prayers of the synagogue were called "eulogies," because to each prayer was joined a thanksgiving. Hence the prayers of the Christian Church also were called blessings and giving of thanks. This illustrates Col 4:2; 1Th 5:17, 18. So the Kaddisch and Keduscha, the synagogue formulæ of "hallowing" the divine "name" and of prayer for the "coming of God's kingdom," answer to the Church's Lord's Prayer, repeated often and made the foundation on which the other prayers are built [Tertullian, Prayer].
