Like honey on her tongue

Thy lips, O my spouse, drop as the honeycomb: honey and milk are under thy tongue... Song of Solomon 4:11 KJV

Like tongues of flame

Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them. Acts 2:2-4 NIV

Regarding angels he says, "The messengers are winds, the servants are tongues of fire." Hebrews 1:7 MSG
