When our ancestors were in Egypt, they gave no thought to your miracles; they did not remember your many kindnesses, and they rebelled by the sea, the Red Sea. (NIV)
Our fathers in Egypt understood not nor appreciated Your miracles; they did not [earnestly] remember the multitude of Your mercies nor imprint Your loving-kindness [on their hearts], but they were rebellious and provoked the Lord at the sea, even at the Red Sea. [Exod. 14:21.] (AMP)
Our fathers understood not thy wonders in Egypt; they remembered not the multitude of thy mercies; but provoked him at the sea, even at the Red sea. (KJV)
