1 tn After verbs of perception, as with “I know” here, the object may be a noun clause introduced with the particle כִּי (ki) – “I know that….” Gesenius observes that the object clause may have a kind of accusative and an infinitive construction (especially after נָתַן [natan] with the idea of “allow”): “he will not permit you to go” (see GKC 491 §157.b, n. 2).
2 tn Heb “and not with a mighty hand.” This expression (וְלֹא בְּיָד חֲזָקָה, vÿlo’ vÿyad khazaqa) is unclear, since v. 20 says that God will stretch out his hand and do his wonders. Some have taken v. 19b to refer to God’s mighty hand also, meaning that the king would not let them go unless a mighty hand compels him (NIV). The expression “mighty hand” is used of God’s rescuing Israel elsewhere (Exod 6:1, 13:9, 32:11; but note also Num 20:20). This idea is a rather general interpretation of the words; it owes much to the LXX, which has “except by a mighty hand,” though “and not with” does not have the meaning of “except” or “unless” in other places. In view of these difficulties, others have suggested that v. 19b means “strong [threats]” from the Israelites (as in 4:24ff. and 5:3; see B. Jacob, Exodus, 81). This does not seem as convincing as the first view. Another possibility is that the phrase conveys Pharaoh’s point of view and intention; the Lord knows that Pharaoh plans to resist letting the Israelites go, regardless of the exercise of a strong hand against him (P. Addinall, “Exodus III 19B and the Interpretation of Biblical Narrative,” VT 49 : 289-300; see also the construction “and not with” in Num 12:8; 1 Sam 20:15 and elsewhere). If that is the case, v. 20 provides an ironic and pointed contradiction to Pharaoh’s plans as the Lord announces the effect that his hand will have. At any rate, Pharaoh will have to be forced to let Israel go.
4 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.
5 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.
