How do we know God was with Joseph?

In Genesis 39:2, it explicitly states, 'And the Lord was with Joseph, and he was a prosperous man.' This signifies that despite being in a foreign land and facing betrayal, Joseph's relationship with God granted him favor and success. God's presence with Joseph was a testament to His promise to never leave His people, illustrating that true prosperity comes from being in a right relationship with God. This assurance is also seen in the New Testament where God promises His presence to all believers.
