Nahum 2:6

2:6 The sluice gates are opened;

the royal palace is deluged and dissolves.

Psalms 107:16

and hacked through the iron bars.

Isaiah 45:1-2

45:1 This is what the Lord says to his chosen one,

to Cyrus, whose right hand I hold

in order to subdue nations before him,

and disarm kings,

to open doors before him,

so gates remain unclosed:

45:2 “I will go before you

and level mountains.

Bronze doors I will shatter

and iron bars I will hack through.
