Deuteronomy 1:10-11

The Lord your God has increased your population to the point that you are now as numerous as the very stars of the sky.  Indeed, may the Lord, the God of your ancestors, make you a thousand times more numerous than you are now, blessing you just as he said he would!

This is Moses, speaking to Israel about becoming, "as numerous as the stars!" (NLT) God's promise to Abraham was to make a nation as numerous as the stars in the sky. Moses recognizes that this is a fulfillment of what God promised to Abraham long ago. This verse is also in the midst of Moses recognizing that he cannot be the sole judge of Israel, because there is too many people. God agrees that Moses should appoint "judges" over the tribes of Israel to help with this role. God is blessing Israel, and the need for strong leadership is becoming more and more important.
