Adam Clarke on Galatians 4:20

I desire to be present with you - I wish to accommodate my doctrine to your state; I know not whether you need stronger reprehension, or to be dealt with more leniently.

I stand in doubt of you - I have doubts concerning your state; the progress of error and conviction among you, which I cannot fully know without being among you, This appears to be the apostle's meaning, and tends much to soften and render palatable the severity of his reproofs.
