Isaiah 5:30

And in that day
<03117>

they shall roar
<05098> (8799)

against them like the roaring
<05100>

of the sea
<03220>_:

and if [one] look
<05027> (8765)

unto the land
<0776>_,

behold darkness
<02822>

[and] sorrow
<06862>_,

and the light
<0216>

is darkened
<02821> (8804)

in the heavens
<06183>

thereof. {sorrow: or, distress} {and the light...: or, when it is light, it shall be dark in the destructions thereof}

Isaiah 27:1

In that day
<03117>

the LORD
<03068>

with his sore
<07186>

and great
<01419>

and strong
<02389>

sword
<02719>

shall punish
<06485> (8799)

leviathan
<03882>

the piercing
<01281>

serpent
<05175>_,

even leviathan
<03882>

that crooked
<06129>

serpent
<05175>_;

and he shall slay
<02026> (8804)

the dragon
<08577>

that [is] in the sea
<03220>_.

{piercing: or, crossing like a bar}
