'Excuse' in the Bible

The men were terrified as they were being taken to Joseph's palace. "It's because of that money that was returned to our sacks the first time we were brought to him," they reasoned. "He's seeking an excuse to attack us, enslave us, and confiscate our donkeys!"

Never let your mouth cause you to sin and don't proclaim in the presence of the angel, "My promise was a mistake," for why should God be angry at your excuse and destroy what you've undertaken?
