'Gums' in the Bible

“My bone clings to my skin and to my flesh,And I have escaped [death] by the skin of my teeth.

The roof of my mouth is as dry as a piece of pottery; my tongue sticks to my gums. You set me in the dust of death.

And when He had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb (Christ), each one holding a harp and golden bowls full of fragrant incense, which are the prayers of the saints (God’s people).

Another angel came and stood at the altar. He had a golden censer, and much incense was given to him, so that he might add it to the prayers of all the saints (God’s people) on the golden altar in front of the throne.
