Psalm 68:4 (ESV),
4 Sing to God, sing praises to his name; lift up a song to him who rides through the deserts; his name is the LORD; exult before him!
The Hebrew text for the phrase emboldened above, i.e. "his name is the LORD" is as follows (from right to left):
At the beginning of the Divine Name, "Yah", the Hebrew letter ב (bet) is present. Does the presence of ב (bet) before the name "Yah" in Psalm 68:4 therefore constitute an example of a Beth Essentiae?
If it does so constitute, what is the correct way to interpret and understand the phrase?
If it does not, why does it not so constitute?
