It comes from my perception of a broken heart and acts 2:37 renders it "cut to the heart" and "pierced to the heart," and Pharoah was not so "inhuman" to be unaffected by such an event. In the acts case, this compelled the people to ask, "what shall we do?" and in Pharoah's case, he already knew what had been asked and released the Israelites.I understand what you are saying. I'm asking for the particular phrase or sentence that carries the meaning of a "pricked heart".
I get that you are reluctant to accept anything but the exact words, but thanks for the opportunity to share this perspective with other interested readers that have not already pledged their allegiance to any particular messenger and all that he (or she) proposed scripture to say.
