Exodus 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.

¹ tn The emphasis on sequence is clear because the form is the perfect tense with the vav consecutive.

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.
