21:1 To the chief Musician, A Psalm of David. The king shall a joy in thy strength, O LORD; and in thy salvation how greatly shall he rejoice!
(a) When he will overcome his enemies, and so be assured of his calling. 21:3 For thou b preventest him with the blessings of goodness: thou settest a crown of pure gold on his head.
(b) You declared your liberal favour toward him before he prayed. 21:4 c He asked life of thee, [and] thou gavest [it] him, [even] length of days for ever and ever.
(c) David not only obtained life, but also assurance that his posterity would reign forever. 21:6 For thou hast made him most d blessed for ever: thou hast made him exceeding glad with thy countenance.
(d) You have made him your blessings to others, and a perpetual example of your favour forever. 21:8 e Thine hand shall find out all thine enemies: thy right hand shall find out those that hate thee.
(e) Here he describes the power of Christs kingdom against the enemies of it. 21:9 Thou shalt make them as a fiery oven in the time of thine anger: the LORD shall swallow them up in his f wrath, and the fire shall devour them.
(f) This teaches us patiently to endure the cross till God destroys the adversary. 21:11 For they g intended evil against thee: they imagined a mischievous device, [which] they are not able [to perform].
(g) They laid as it were their nets to make Gods power bend to their wicked enterprises. 21:12 Therefore shalt thou make them h turn their back, [when] thou shalt make ready [thine arrows] upon thy strings against the face of them.
(h) As a mark to shoot at. 21:13 i Be thou exalted, LORD, in thine own strength: [so] will we sing and praise thy power.
(i) Maintain your Church against your adversaries that we may have ample opportunity to praise your Name.
