"Take this cup" in the Bible: Luke 22:41-43
Before Jesus went to the cross, he spent time alone praying to God and asking to "take this cup from me." It's important to note that while he asked God to take the cup from him, he immediately added that it should be God's will that would be done, not his own. After his petition, the angles came to give him strength.
