In 1 Corinthians 12:31 and 1 Corinthians 14:39, the word is ζηλόω, and is quite different from the coveting that is condemned in scripture; it is translated in Revelation 3:19 “be zealous,” and the above passages in Corinthians can be so translated, or “desire earnestly” the best gifts, and “desire earnestly” to prophesy.
