In this verse, the Israelites are reminded of the miraculous events they witnessed during their exodus from Egypt. These events included great trials, signs, and wonders that demonstrated God's mighty power and His commitment to their deliverance. The 'mighty hand and outstretched arm' symbolize God's active and powerful intervention in human history, specifically in liberating His people from bondage.
This reminder serves a dual purpose: it reinforces the Israelites' faith in God's ability to protect and deliver them, and it assures them that the same divine power will be used against the nations they fear as they enter the Promised Land. The message is one of reassurance and encouragement, emphasizing that God's past actions are a guarantee of His future faithfulness. This verse invites believers to reflect on God's past faithfulness in their own lives and to trust in His ongoing presence and power in facing current challenges.
