Psalms 48:3

God is known in her palaces for a refuge - All those who worship there in spirit and truth, find God for their refuge. But the words may be understood: God is known for the defense of her palaces; and with this view of the subject agree the three following verses.

God is known in her palaces - The word rendered "palaces" here means properly a fortress, castle, or palace, so called from its height, from a verb, ארם 'âram, meaning to elevate, to lift up. It may be applied to any fortified place, and would be particularly applicable to a royal residence, as a castle or stronghold. The word "known" here means that it was well understood, or that the point had been fully tested and determined that God had chosen those abodes as his special residence - as the place where he might be found.

For a refuge - See the notes at Psalm 46:1. That is, there was safety or security in the God who had chosen Jerusalem as his special abode.

48:3 Known - By long experience. Palaces - Possibly he may point at the king's palace and the temple, which was the palace of the king of heaven; which two palaces God did in a singular manner protect, and by protecting them, protected the whole city and people.
