It’s used that way several times in the scriptures: Christ told John the Baptist, “Suffer it to be so now…” meaning, permit the baptism to take place. The Lord “suffered” the U.S. Constitution to be established, to help accomplish some of His own purposes. To be “longsuffering” is to be patient and forbearing.

Here, Christ was allowing something to happen—allowing his execution—in order to bring about the resurrection. That he also suffered in the other sense—by enduring agony—doesn’t seem DIRECTLY relevant to the issue posed here.
