What Did Yisrael Attain at the Splitting of the Sea?

“Ze keli v'anvehu — This is my G-d, and I will exalt Him”  (Pesukei Dzimra) 

The word “this” denotes clarity of perception and Ture Knowledge, as if they were viewing the Shechina (Divine Presence) and pointing to it with the finger; for such was the elevated knowledge of Hashem which they attained at that wondrous time of the splitting of the sea. — Praise, My Soul
