This question is about Daniel Webster's Seventh of March Speech
Answer:
He is referring to the possibility of the country's secession, in addition to referring to slavery as something immoral and incorrect. According to his reasoning, slavery is blamed by God and to share a territory as rich and vast as the USA would be an act of insanity.
Step-by-step explanation:
On March 7, 1850, Webster delivered a speech to the US Senate Chamber reinforcing the need for cooperation and unity across the country to combat slavery and prevent the dismemberment of southern states. For him, the federal government had to act and prevent these problems from happening.
For Webster, slavery is forbidden by God and this is written in the Bible, moreover, he stated that God presented Americans with a vast and rich territory and separating it so irrationally was a stupid act and without intelligence.
