dictionary mentioned by leonard ravenhill

hi guys, i was wondering if someone could help me out with something. there was a sermon by brother ravenhill (which i cannot recall) where he mentioned a good dictionary that was printed a while ago. he was mentioning how much words have changed over time and recommended buying this older one. anyone know what i'm talking about? if you happen to know that would be a huge blessing to me! thanks and God bless!

Noah Webster's 1828 Dictionary, is good for KJV
