Exodus 3:20

3:20 So I will extend my hand ¹  and strike Egypt with all my wonders ²  that I will do among them, and after that he will release you. ³ 

Genesis 15:14

15:14 But I will execute judgment on the nation that they will serve. ⁴  Afterward they will come out with many possessions.

[3:20]  ¹ sn The outstretched arm is a bold anthropomorphism. It describes the power of God. The Egyptians will later admit that the plagues were by the hand of God (Exod 8:19).

[3:20]  ² tn The word נִפְלְאֹתַי (niflÿ’otay) does not specify what the intervention will be. As the text unfolds it will be clear that the plagues are intended. Signs and portents could refer to things people might do, but “wonders” only God could do. The root refers to that which is extraordinary, surpassing, amazing, difficult to comprehend. See Isa 9:6; Gen 18:14; Ps 139:6.

[3:20]  ³ sn The two uses of the root שָׁלָח (shalakh) in this verse contribute to its force. When the Lord “sends” (Qal) his hand, Pharaoh will “send” (Piel) the Israelites out of Egypt.

[15:14]  ⁴ tn The participle דָּן (dan, from דִּין, din) is used here for the future: “I am judging” = “I will surely judge.” The judgment in this case will be condemnation and punishment. The translation “execute judgment on” implies that the judgment will certainly be carried out.
