PSALM CI.
Vers 1. I Will sing of mercy and judgement, &c.] Two severall waies this promise of David is expounded by Interpreters, and both seem very probable: to wit, 1. that David doth here promise to praise God for his goodnesse and mercy to his penitent servants, and for his judgements executed upon the obstinate and rebellious; or more particularly for the judgement which God had executed upon Saul, (for some conceive that this Psalm was composed when Saul was newly cut off by the Philistines) or which he knew God would execute upon him, and the mercy which he had shewn to himself, in preserving him from the rage of Saul, and haply for opening such a fair way for the settling of him in the throne of Israel; or at least the mercy which he knew God would shew him, in bringing him to the kingdome long since promised him: and then the follow∣ing clause is clear; unto thee, O Lord, will I sing, that is, I will speak of these things to thy praise and glory: Or 2. that David doth here undertake, that he would in this Psalm, as it were by way of a vow to God, and a solemn protestation before all the Church, declare with what clemency and justice he meant to govern the kingdome, when he should be settled in the throne; how gentle and good every way he would be to the good, and how zealous to punish the wicked. And if we take it thus, which seems most agreeable to the sequele of the Psalm, then the mea∣ning of the following clause seems to be this; unto thee, O Lord, will I sing, that is, I will in my song thus engage my self, out of a desire thereby to glorify thee, by whom only I was appointed to so great honour, and by whose grace only I hope to be enabled thus to govern the kingdome.
Vers. 2. I will behave my self wisely in a perfect way, &c.] To wit, by avoiding what ever is evil with all possible circumspection. And indeed this is expresly af∣firmed of David in his private life, 1 Sam. 18.14. And David behaved himself wisely in all his waies.
O when wilt thou come unto me?] To wit, to assist me with thy grace herein; or rather, to settle me in the kingdome promised me, that I may then make good
