Psalm 2 is a song-like poem that talks about how important and powerful God is. It tells us that the people who don't believe in God will someday realize they made a mistake and feel very sorry for not following God's rules. The poem also says that God has chosen a special person, called a king, to help rule the land and make sure everyone follows God's rules. The poem talks about how happy and safe people will be if they follow God and listen to the king. It reminds us that God loves us very much and wants us to be good and kind to each other. Just like how a parent wants their child to behave properly, God wants us to do good things and be happy.
