1 Corinthians 14:21

It is written, etc. From Isaiah 28:11; Isaiah 28:12. The quotation does not correspond exactly either to the Hebrew or to the Septuagint. Heb., with stammerings of lip. Sept., By reason of contemptuous words of lips. Paul omits the Heb. : This is the rest, give ye rest to the weary, and this is the repose. Sept. : This is the rest to him who is hungry, and this is the ruin. The point of the quotation is that speech in strange tongues was a chastisement for the unbelief of God's ancient people, by which they were made to hear His voice "speaking in the harsh commands of the foreign invader." So in the Corinthian Church, the intelligible revelation of God has not been properly received.
