John Gill Commentary Isaiah 30:10

"that say to the seers, See not; and to the prophets, Prophesy not unto us right things, speak unto us smooth things, prophesy deceits," — Isaiah 30:10 (ASV)

Which say to the seers, See not The same with the prophets in the next clause, which explains this: and to the Prophets, prophesy not unto us right things ; things agreeable to the mind and will of God, and which ought to be done; not that they, in so many words, said this, but this was the language of their hearts and actions.

The Targum is, ``who say to the prophets, prophesy not, and to the teachers, teach us not the doctrine of the law:''

speak unto us smooth things ; that peace and prosperity should attend them, though they went on in their sinful courses:

prophesy deceits ; for to prophesy peace to them, when destruction was at hand, was to deceive them; and yet they chose rather to be told the one than the other.
