When Moses was 120 years old he told the Isrealites Joshua would take his place as leader. He told them to not sin and follow God. He also honored God with a song. Here is how it started:
“Listen, O heavens, and I will speak!
Hear, O earth, the words that I say!
2 Let my teaching fall on you like rain;
let my speech settle like dew.
Let my words fall like rain on tender grass,
like gentle showers on young plants.
3 I will proclaim the name of the Lord;
how glorious is our God!
4 He is the Rock; his deeds are perfect.
Everything he does is just and fair.
He is a faithful God who does no wrong;
how just and upright he is!
