Where can I find the word 'Jehovah Rapha' in the bible?

Jehovah Rapha can be found in the Bible, however it cannot be found in any modern translation (i.e. NIV, ESV) because of the translation method. The word Jehovah Rapha does appear in the Masoretic Text, which is the Old Testament manuscripts which have been maintained by the Levite priests since the original manuscript was written.

In the Hebrew(Read from right to left) of Exodus 15:26:

"ויאמר אם שׁמוע תשׁמע לקול יהוה אלהיך והישׁר בעיניו תעשׂה והאזנת למצותיו ושׁמרת כל חקיו כל המחלה אשׁר שׂמתי במצרים לא אשׂים עליך כי אני יהוה רפאך׃"

The phrase "יהוה רפאך" is transliterated as "Jehovah Rapha".
