Galatians 4:15

Where is then the blessednessye spake of] The last three words are not in the original. They are a paraphrase (and so an interpretation) of the genitive of the 2nd personal pronoun. Does this genitive express the objector the subjectof the noun rendered -blessedness"? This noun occurs Romans 4:6. Here it may either mean -your blessedness" (as A.V.), the blessedness which you experienced in embracing the Gospel of justification by faith apart from the works of the law. Or it may mean, your applause of me. On the whole the former is to be preferred, as bearing on the general argument of the Epistle. The latter is however in full accordance with the immediate context.

your own eyes Rather, your eyes. Some have inferred from the A.V. that St Paul was suffering from loss of eyesight. But the emphasis is not on -your" but on -eyes". -There is no sacrifice which you were not ready to make to shew your zeal and affection towards me".
