'Dissembled' in the Bible

Israel hath sinned, and they have also transgressed my covenant which I commanded them: for they have even taken of the accursed thing, and have also stolen, and dissembled also, and they have put it even among their own stuff.

For ye dissembled in your hearts, when ye sent me unto the LORD your God, saying, Pray for us unto the LORD our God; and according unto all that the LORD our God shall say, so declare unto us, and we will do it.
