Exodus 37:3-5

King James Version

³ And he cast for it four rings of gold, to be set by the four corners of it; even two rings upon the one side of it, and two rings upon the other side of it.

⁴ And he made staves of shittim wood, and overlaid them with gold.

⁵ And he put the staves into the rings by the sides of the ark, to bear the ark.
