John Gill Reformed Baptist @doctorgill

Ye shall offer no strange incense thereon,.... Which had not the same, but was made of other materials, or had more or fewer; whatever was not exactly the same was not to be offered; and so to make use of other mediators than Christ, whether angels or men, or to put up prayer to God for the sake of our own righteousness, pleading the merits...

Jamieson-Fausset-Brown Reformed @jfbcommentary
