Isaiah 11 is a chapter in the Bible where a prophet named Isaiah talks about a special person called the "branch" who will come from a family tree. The branch will be very special and will have wisdom, understanding, strength, knowledge, and fear of God.
This branch will be like a king who will rule over everyone and bring peace to the world. The branch will help animals become friends, like a lion and a lamb who will play together. This is like when you make friends with someone who might be different than you, but you both still have fun and get along.
The branch will also help people who are poor and don't have anything. They will not be left alone, they will be taken care of by the branch.
Isaiah says that this branch will be really important and will change the world. People will hope for him to come and they will want to be with him.
