The third strophe turns to examples drawn from the great ones of old, which at once encourage to worship and teach the true nature of worship, while they also set in clear light Jehovah's holiness in dealing with His worshippers. Priestly functions were exercised by Moses, as in sprinkling the blood of the covenant (Exod. xxiv.), and in the ceremonial connected with the consecration of Aaron and his sons (Lev. viii.), as well as at the first celebration of worship in the Tabernacle (Exod. xl. 18 _sqq._). In the wider sense of the word _priest_, he acted as mediator and intercessor, as in Exod. xvii. 12, in the fight against Amalek, and xxxii. 30-32, after the worship of the golden calf. Samuel, too, interceded for Israel after their seeking a king (1 Sam. xii. 19 _sqq._), and offered sacrifices (1 Sam. vii. 9). Jeremiah couples them together as intercessors with God (xv. 1). From these venerable examples the psalmist draws instruction as to the nature of the worship befitting the holiness of Jehovah. He goes deeper than all sacrifices, or than silent awe. To call on God is the best adoration. The cry of a soul, conscious of emptiness and need, and convinced of His fulness and of the love which is the soul of His power, is never in vain. "They called, and He"--even He in all the unreachable separation of His loftiness from their lowliness--"answered them." There is a commerce of desire and bestowal between the holy Jehovah and us. But these answers come on certain conditions, which are plain consequences of His holiness--namely, that His worshippers should keep His testimonies, by which He has witnessed both to His own character and to their duty. The psalmist seems to lose sight of his special examples, and to extend his view to the whole people, when he speaks of answers from the pillar of cloud, which cannot apply to Samuel's experience. The persons spoken of in ver. 8 as receiving answers may indeed be Moses, Aaron, and Samuel, all of whom were punished for evil deeds, as well as answered when they cried; but more probably they are the whole community. The great principle, firmly grasped and clearly proclaimed by the singer, is that a holy God is a forgiving God, willing to hearken to men's cry, and rich to answer with needed gifts, and that indissolubly interwoven with the pardon, which He in His holiness gives, is retribution for evil. God loves too well to grant impunity. Forgiveness is something far better than escape from penalties. It cannot be worthy of God to bestow or salutary for men to receive, unless it is accompanied with such retribution as may show the pardoned man how deadly his sin was. "Whatsoever a man soweth that shall he also reap" is a law not abrogated by forgiveness. The worst penalty of sin, indeed--namely, separation from God--is wholly turned aside by repentance and forgiveness; but for the most part the penalties which are inflicted on earth, and
