then hear their prayer and their supplication in heaven Your dwelling place, and maintain their right and defend their cause,

And may what I've had to say to the LORD remain with the LORD our God both day and night, so that he may defend the cause of his servant and the cause of his people Israel, as the need of the day may require it,
