“How could we sing Yahweh’s song
In a foreign land?
If I forget you,
Let my right hand wither!
Let my tongue cleave to the roof of my mouth,
If I do not remember you,
If I do not set Jerusalem
Above my highest joy.”
The psalmist asked how he could sing a song about Yahweh when he was in a foreign land. If he had forgotten Jerusalem, his right hand should wither. His tongue should stick to the roof of his mouth. He was always going to remember Jerusalem as his greatest joy. He would never forget that wonderful place.
