“He will hide me in his shelter.
In the day of trouble,
He will conceal me
Under the cover of his tent.
He will set me high on a rock.”
Yahweh will protect David. He will hide him in his shelter. If ever there was any trouble, Yahweh would hide him under his tent. On the other hand he might protect him by putting him high on a rock. The tent and the high rock might be reference to the Temple on Mount Zion.
