The Explicit Name
The 72 angelic names are obtained from Exodus Chapter 14, verses 19, 20, and 21. Each verse contains 72 hebrew letters.
If each verse is given its own row, one above the other, it will form 72 columns, with three letters in each column.
Using Gematria, Verse 19 is written from right to left, Verse 20 from left to right, and Verse 21 from right to left.
This is called the Shem Ha M'phoresh, abbreviated "Shem Ha", or the 72 angel names.
You will see deliberate empty spacing in the Torah scrolls, indicating that there is something special encoded.
Angel names ending in -iah is Mercy and Feminine.
Angel names ending in -el is Judgement and Masculine.
