How do we know Jesus is depicted as the captain of the Lord's host?

In Joshua 5:14, the figure with a drawn sword, identified as 'the captain of the Lord's host,' makes a significant appearance to Joshua. This figure is understood as a pre-incarnate appearance of Christ, affirming His divine authority and leadership over the armies of Israel. The acceptance of Joshua's worship further confirms His identity as the Lord, as angels do not accept worship meant for God alone. This encounter serves as a reminder of Christ’s ongoing role as the leader and protector of His people, illustrating how God directly engages with His people throughout history. Thus, in recognizing Jesus as the captain, believers can find assurance and strength in His leadership.
