"They shall see and rejoice, those who fear You, etc. When do the people of Israel rejoice? When they see their king or president engaging in Torah study. As it is written (Psalms 35:27), 'Those who desire my vindication shall shout for joy and be glad.' And what is written afterwards (Psalms 35:28), 'My tongue shall speak of Your righteousness, and of Your praise all day long.' Therefore, as long as the king is engaged in Torah study, the people of Israel are happy. Therefore it is said, 'They shall see and rejoice, those who fear You, etc.'"
