Exodus 11:9-10

  9 H3068 And the LORD H559 said H4872 to Moses, H6547 Pharaoh H8085 shall not listen H4159 to you; that my wonders H7235 may be multiplied H776 in the land H4714 of Egypt.

  10 H4872 And Moses H175 and Aaron H6213 did H3605 all H428 these H4159 wonders H6440 before H6547 Pharaoh: H3068 and the LORD H2388 hardened H6547 Pharaoh’s H3820 heart, H1121 so that he would not let the children H3478 of Israel H7971 go H776 out of his land.
