Psalms 122:5

For there are set thrones of judgment, the thrones of the house of David; for Jerusalem was not only the seat of the Sanctuary of Israel, but also the capital city of the nation, where the highest government officials resided, where, above all, the administration of justice was the original and chief duty of the monarch in times of peace. The psalmist, having thus painted a picture of Jerusalem, the capital, which also contained the Sanctuary of the nation, is constrained to send up a prayer for its continued well-being.
