Psalms 67:4 - Matthew Poole's English Annotations on the Holy Bible

Be glad and sing for joy, for thy transcendent mercy to them, in rescuing them from the vanities and damnable errors of their fathers, and in bringing them to the knowledge of the true God, and of eternal life. Shalt judge, i.e. rule and govern them, as it is explained in the next clause, and as this phrase is used. Righteously; which is the great commendation of any government, and the greatest argument and encouragement to the Gentiles to put themselves under it; the rather, because they had found the misery of living under the unrighteous and tyrannical government of the devil, and of their idolatrous and heathenish rulers. Govern, Heb. lead, to wit, gently, as a shepherd doth his sheep; and not rule them with rigour, as other lords had done.
