Chasidut su II Re 8:6

The splitting of the Red Sea corresponds to Rabbeinu z"l's teaching in this lesson on 'G-d shed two tears into the great sea'. This means that He draws providence to subdue the nations, which correspond to the sea, as written (Isaiah 57:20) "the wicked are swept away like the sea", which brings about miracles and wonders, which are called 'great' as written (II Kings 8:6) "tell me of the great deeds". This is represented by the splitting of the Red Sea when there was a great revelation of providence. By means of providence came the miracle, providence that G-d drew came upon the sea which corresponds to the nations and the sea split. In other words, the splitting of the Red Sea took place on two levels, two that are one, for they are inter-dependent. The splitting of the Red Sea alludes that the sea of wisdom above was split, and knowledge, corresponding to providence, was revealed, for providence is the quintessential knowledge. This same dynamic also split the sea below, which alludes to the nations of the world who are swept away like the sea-they were all split, broken and eliminated, while Israel passed through the sea on dry land. The waters, representing the nations, could not wield power over Israel, since providence was revealed, as in, 'G-d shed two tears into the great sea'. For Pharaoh had gained power through the two letters מ'י' which spells י"ם (sea) and therefore he said "who is G-d that I should listen to him?} (Exodus 5:2) as stated in the Ari z"l's writings. Therefore Pharaoh was subdued mainly by the revelation of Providence with the splitting of the Red Sea as in, 'G-d sheds two tears', which is Providence, into the great sea.
