Isaiah 30:20
And though the Lord give you the bread of adversity, and the water of affliction, yet shall not thy teachers be removed into a corner any more, but thine eyes shall see thy teachers: And though the Lord give you the bread of adversity, and the water of affliction, yet shall not thy teachers be removed into a corner any more, but thine eyes shall see thy teachers:
The bread of adversity and the water of affliction mean that trial and affliction are the common lot of all of God's people. The militant church is called to suffer trial and affliction, struggling toward triumph and moving toward it only through severe conflict. Those who put their trust in God, who is mighty to deliver, will not be utterly overwhelmed by these trials.
The verse promises that God will have a remnant people who will be purified, made white, and tried. Even when the Lord gives them the bread of adversity and the water of affliction, their true teachers will not be removed into a corner anymore, but their eyes will see their teachers. Their ears will hear a word behind them telling them the right way to walk when they turn to the right hand or to the left.
