Psalms 71:21

Thou shalt increase my greatness,.... His temporal greatness, as he did, by crushing the rebellion of his son; returning him to his palace and family; and giving him rest from his enemies all around: and his spiritual greatness, by favouring him with his presence; by shedding abroad his love in his heart; by enlarging his experience; increasing his faith, causing his love to abound, and him to grow in every grace, and in the knowledge of Christ;

and comfort me on every side; by his Spirit, word, and ordinances; by his truths and promises; with his rod and staff; and with mercy, grace, and lovingkindness. The phrase denotes the abundance of comfort, which should come as it were from every quarter, and encompass him about.
