Charles H. Spurgeon on Psalms 50:8

I will not reprove thee for thy sacrifices or thy burnt offerings continually before me. Those words to have been, which our translators supply, may be left out, and the sense remain perfect: or if those words be continued, then the negative particle not, is to be reassumed out of the first part of the verse, and the whole read thus, I will not reprove thee for thy sacrifices, or thy burnt offerings not to have been continually before me. That is, I will not charge thee with a neglect of outward duty or worship, the inward or spiritual (of which he speaks, Ps 50:14), being that which is most pleasing unto me. Joseph Caryl.

Verses 8-9. It is the very remonstrance which our Lord himself makes against the Pharisees of his days, for laying so much stress on the outward observance of their own traditions, the washing of pots and cups and other such like things; the paying of tithes of anise and mint and cummin; the ostentatious fulfilment of all ceremonious observances in the eyes of men, the exalting the shadow to the exclusion of the substance. And have we not seen the like in our own days, even to the very vestment of the minister, the obeisance of the knee, and the posture of the body? as if the material church were all in all, and God were not Spirit, that demanded of those that worshipped him that they should worship him in spirit and in truth; as if the gold and ornaments of the temple were far beyond the hidden man of the heart in that which is incorruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price. Barton Bouchier.
