Passage
Instead of the thorn come up doth fir, Instead of the brier come up doth myrtle, And it hath been to Jehovah for a name, For a sign age-during--it is not cut off!
Instead of the thorn come up doth fir, Instead of the brier come up doth myrtle, And it hath been to Jehovah for a name, For a sign age-during--it is not cut off!
Isaiah 55:11 So is My word that goeth out of My mouth, It turneth not back unto Me empty, But hath done that which I desired, And prosperously effected that <FI>for<Fi> which I sent it.
Isaiah 55:12 For with joy ye go forth, And with peace ye are brought in, The mountains and the hills Break forth before you <FI>with<Fi> singing, And all trees of the field clap the hand.
Isaiah 55:13 Instead of the thorn come up doth fir, Instead of the brier come up doth myrtle, And it hath been to Jehovah for a name, For a sign age-during--it is not cut off!
The verse centers on "instead", "thorn", "come", "doth", and "brier". It is saying that the verse draws attention to "instead" and "thorn", so its meaning should be read from those terms before moving to application.
The prior verse says "For with joy ye go forth And...", giving immediate footing for "instead" and "thorn". In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "instead" and "thorn" with trust shaped by these words, not by a vague optimism outside the passage.
