With Shevii shel Pesach around the corner, which marks the splitting of the Yam Suf, here is an astonishing observation.
The term "keria," splitting, which is how the miracle is known, i.e. kerias Yam Suf, קריעת ים סוף, does not appear in Tanach. It is a much later word used by the Sages almost exclusively scores of times and is quoted by Rashi.
What is used in Tanach to refer to the splitting of the sea is the root בקע as the verse that describes the event says, ""נטה את ידך על הים ובקעהו" stretch out your hand and split it," and גזר as in "לגוזר ים סוף לגזרים."
When googling this, you can find articles that explain why this is so.
