Not all that is in there is infallible, but unlike the works of Matthew Henry, Keil & Delitzsch, Jamieson, Fausset and Brown, Barnes, Clarke, etc. there can be found infallible teachings within them.
Peace be with you.
If she does say so herself, but your acknowledgement that all is not infallible in them (which i knew), or nor are they a complete commentary, affirms what i was claiming.
