What does Joshua 14:10 mean?

Look, the Lord has kept me alive just like he promised. It’s been forty-five years since he told Moses about this, back when Israel was wandering in the desert. And here I am today, eighty-five years old. Joshua 14:10 - Modern Text Bible

(Caleb is speaking, reminding everyone that God has kept his promise to let him live through all the years since the Israelites left Egypt. He’s emphasizing his age and God’s faithfulness.)
