If integrated into the book of Daniel: 3.80

All birds of the air is reduced by Good News Translation to “all birds,” with of the air considered redundant. Although there are some birds that do not fly, the poem is not concerned with such distinctions, so Contemporary English Version has “Each bird in the sky.”
