In the West, it is also the last week of Lent, & includes Palm Sunday, Holy Wednesday, Maundy Thursday (Holy Thursday), Good Friday (Holy Friday), & Holy Saturday. It does not include Easter Sunday, which begins the season of Eastertide, although traditions observing the Eastertide may vary in different liturgical customs.
John The Baptist saw Jesus coming toward him and said, “Look, the Lamb of God who takes away the sin of the world. I have seen and I testify that this is the Son of God.” (John 1:29,34). John the Baptist had been preaching about the coming Messiah, identifying himself as the forerunner Isaiah had promised over 700 years earlier. In Isaiah 40:3 John said, “I am the voice of one calling in the desert, ‘Make straight the way for the Lord ‘ “ (John 1:23). Introducing Jesus to Israel as the Lamb of God would prompt a comparison between Jesus and the Passover lamb in their minds.
