Daniel 9:27 and the Confirmation of a Covenant
“Just aware of the wording of this verse. (Dan 9:27) The huge difference between ‘confirming’ an agreement and ‘making’ an agreement. It seems to leave an opening for deception. The covenant could be made and the anti-Christ could have absolutely nothing to do with it, and then after an unspecified time, he could come in and ‘sign on’ to an already existing covenant. But would it not be very unusual to come in to a covenant and confirm it, but with a time limit of 7 years?
