It’s too easy to look elsewhere for help. In doing so, Judah was destined to bring calamity onto itself. God’s view on this wasn’t positive:
Isaiah 30:15 This is what the Sovereign Lord,
the Holy One of Israel, says:
‘Only in returning to me
and resting in me will you be saved.
In quietness and confidence is your strength.
But you would have none of it.’
The result was to be destruction for Judah: if they relied on Egypt rather than on God, then it meant He couldn’t help them. Instead, he had to wait to be able to help:
Isaiah 30:18-19So the Lord must wait for you to come to him
so he can show you his love and compassion.
For the Lord is a faithful God.
Blessed are those who wait for his help.
O people of Zion, who live in Jerusalem,
you will weep no more.
He will be gracious if you ask for help.
He will surely respond to the sound of your cries.
