To Eulogize someone is to remember them kindly and speak well/ good of them. When Jesus was at the Last Supper with His disciples, it is a part of what they were doing during their celebrations. During Passover they sang and spoke (Mat 26:30 And when they had sung a hymn, they went out into the mount of Olives. ) and most importantly remembered the Mighty Hand of God that saved them from death.
HE is our Victory!
