Keluaran 7:5

7:5 Then ¹  the Egyptians will know that I am the Lord, when I extend my hand ²  over Egypt and bring the Israelites out from among them.

Keluaran 14:4

14:4 I will harden ³  Pharaoh’s heart, and he will chase after them. I will gain honor ⁴  because of Pharaoh and because of all his army, and the Egyptians will know ⁵  that I am the Lord.” So this is what they did. ⁶ 

Keluaran 14:18

14:18 And the Egyptians will know ⁷  that I am the Lord when I have gained my honor ⁸  because of Pharaoh, his chariots, and his horsemen.”

[7:5]  ¹ tn The emphasis on sequence is clear because the form is the perfect tense with the vav consecutive.

[7:5]  sn The use of the verb “to know” (יָדַע, yada’) underscores what was said with regard to 6:3. By the time the actual exodus took place, the Egyptians would have “known” the name Yahweh, probably hearing it more than they wished. But they will know – experience the truth of it – when Yahweh defeats them.

[7:5]  ² sn This is another anthropomorphism, parallel to the preceding. If God were to “put” (נָתַן, natan), “extend” (נָטָה, nata), or “reach out” (שָׁלַח, shalakh) his hand against them, they would be destroyed. Contrast Exod 24:11.

[14:4]  ³ tn In this place the verb חָזַק (hazaq) is used; it indicates that God would make Pharaoh’s will strong or firm.

[14:4]  ⁴ tn The form is וְאִכָּבְדָה (vÿ’ikkavÿda), the Niphal cohortative; coming after the perfect tenses with vav (ו) consecutives expressing the future, this cohortative indicates the purpose of the hardening and chasing. Yahweh intended to gain glory by this final and great victory over the strength of Pharaoh. There is irony in this expression since a different form of the word was used frequently to describe Pharaoh’s hard heart. So judgment will not only destroy the wicked – it will reveal the glory and majesty of the sovereignty of God.

[14:4]  ⁵ tn This is the perfect tense with the vav (ו) consecutive. But it announces the fulfillment of an long standing purpose – that they might know.

[14:4]  ⁶ tn Heb “and they did so.”

[14:18]  ⁷ tn The construction is unusual in that it says, “And Egypt will know.” The verb is plural, and so “Egypt” must mean “the Egyptians.” The verb is the perfect tense with the vav consecutive, showing that this recognition or acknowledgment by Egypt will be the result or purpose of the defeat of them by God.

[14:18]  ⁸ tn The form is בְּהִכָּבְדִי (bÿhikkavÿdi), the Niphal infinitive construct with a preposition and a suffix. For the suffix on a Niphal, see GKC 162-63 §61.c. The word forms a temporal clause in the line.
