Then Pharaoh
<06547>

also called
<07121> (8799)

the wise men
<02450>

and the sorcerers
<03784> (8764)_:

now the magicians
<02748>

of Egypt
<04714>_,

they also did
<06213> (8799)

in like manner
<03651>

with their enchantments

Exodus 15:23

And when they came
<0935> (8799)

to Marah
<04785>_,

they could
<03201> (8804)

not drink
<08354> (8800)

of the waters
<04325>

of Marah
<04785>_,

for they [were] bitter
<04751>_:

therefore the name
<08034>

of it was called
<07121> (8804)

Marah
<04785>_.

{Marah: that is Bitterness}
