Circular reasoning!
It’s not a single drawing. The two tall figures are male and possibly meant to be deities; the cow – contrary to the yellow addition to the drawing – is curious since a cow is female and both Yahweh and Ba’al are male. The reference to Exodus is misleading. It could be meant as Yahweh, if you don’t mind the gender confusion, since Samaritan religion sort of replaced Baal with Yahweh – or merged the two – but that’s a historical question, not a scriptural one.
The seated figure, if the two tall ones are gods, would be the head deity; sitting was regarded as being the one in authority.
The bit on the left looks like it was a horse figure; I don’t know if there’s a gap in the drawing or not, but somehow the front of the horse got cut off. The missing part could be important if it was drawn by the same person who drew the other figures: to the left of the tall central figure are some markings I can’t make sense of since the rest of them is missing in the blank area.
Then under the cow someone later on was making tally marks. The marks in the lower right make no sense to me; I’d guess that parts of the image are missing both below and further right.
To get speculative, the tall figure seems to be standing on the ground while the one behind him could be above water – that little line with two peaks might be meant to depict a wave, in which case this god is either or a shore or is walking or gliding over water.
Oh – last bit: if the cow is meant as a deity I have no idea why the suckling calf. My guess is that the cow and calf are the oldest drawing and had no religious significance, and the gods and horse were added later.
A connection of the drawing to the inscription “Yahweh and his asherah” is doubtful.
