Answer: The right answers are:
1. Giddy=Dizzy
2. Doth=Does
3. On amain=With all His might OR Hastily.
Explanation: Just to elaborate a little on the answer, it can be added that this excerpt from Wigglesworth’s remarkable poem about the final day of Judgement, which was published in 1662—hence the use of some archaic words— the speaker is describing the majestic and blinding arrival of Jesus who comes to judge the living and the dead. Those who witness the dreadful scene from their windows with tears in their eyes have rushed from their beds feeling still dizzy, since they were sleeping.
