Psalms 74:2

Remember thy congregation, [which] thou hast purchased of old; the rod of thine inheritance, [which] thou hast redeemed; this mount Zion, wherein thou hast dwelt.

Ver. 2. Remember thy congregation, which thou hast purchased] His complaints end not in murmuring and grunting against God; but in humble petitions, so intermingled with sighs and groans, as that his speech is not so plain and perfect as at other times. That which he mainly urgeth is the covenant, that hive of heavenly honey, as one calleth it.

The rod of thine inheritance] Inheritances were wont to be measured out by rods and perches. Assyria is the work of God's hands, but Israel (as a further favour) is his inheritance, Isaiah 19:25 .
