Arcana Coelestia # 9675
9675. 'Overlaid with gold' means a representative sign there of good, the good meant by 'the pillars of shittim [wood]'. This is clear from the meaning of 'overlaying with gold', and of 'making from gold', as a representative sign of good, dealt with in 9510.
Pillars of fire
In Revelation 10:1, the reason why the Lord's feet seemed to be 'pillars of fire,' is because the Lord's Divinity on the natural plane -- which fundamentally is the Divine humanity that He took on in the world -- supports His Divinity from eternity, as the body does the soul, and likewise as the Word's natural meaning supports its spiritual and celestial meanings, for 'feet' signify natural things, 'pillars' signify support, and 'fire,' divine love.
