(1) In 1 Corinthians 8:7, AV, "unto this hour," the phrase in the orginal is simply, "until now," as RV
(2) In Revelation 8:1, hemioron, "half an hour" (hemi, "half," and hora), is used with hos, "about," of a period of silence in Heaven after the opening of the 7th seal, a period corresponding to the time customarily spent in silent worship in the Temple during the burning of incense.
