Paul / Saul a double minded man that brought a man created gospel of falsehood & lies - Isaiah 28:15

Isaiah 28:15-19
15 You boast, “We have entered into a covenant with death,
with Saul we have made an agreement.
When an overwhelming scourge sweeps by,
it cannot touch us,
for we have made a lie our refuge
and falsehood our hiding place.”
16 So this is what the Sovereign Lord says:
“See, I lay a stone in Zion, a tested stone,
a precious cornerstone for a sure foundation;
the one who relies on it
will NOT make haste.
17 I will make justice the measuring line
and righteousness the plumb line;
hail will sweep away your refuge, the lie,
and water will overflow your hiding place.
18 Your covenant with death will be annulled;
your agreement with Saul will not stand.
When the overwhelming scourge sweeps by,
you will be beaten down by it.
19 As often as it comes it will carry you away;
morning after morning, by day and by night,
it will sweep through.”
The understanding of this message
will bring sheer terror.
