The seraphim (fiery, burning ones) are angelic beings associated with the prophet Isaiah’s vision of God in the Temple when God called him to his prophetic ministry (Isaiah 6:1-7). Isaiah 6:2-4 records, “Above him were seraphs, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying. And they were calling to one another: ‘Holy, holy, holy is the Lord Almighty; the whole earth is full of his glory.’ At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke.” Seraphs are angels who worship God continually.
Isaiah chapter 6 is the only place in the Bible that specifically mentions the seraphim. Each seraph had six wings. They used two to fly, two to cover their feet, and two to cover their faces (Isaiah 6:2). The seraphim flew about the throne on which God was seated, singing His praises as they called special attention to God’s glory and majesty. These beings apparently also served as agents of purification for Isaiah as he began his prophetic ministry. One placed a hot coal against Isaiah’s lips with the words, “See, this has touched your lips; your guilt is taken away and your sin atoned for” (Isaiah 6:7). Similar to the other types of holy angels, the seraphim are perfectly obedient to God. Similar to the cherubim, the seraphim are particularly focused on worshiping God.
