There is a poor blind Samson

This was a hard poem for me. Mainly just because i'm not good with allusions and i didn't really know this story. But I found that the author of this poem was using Samson to allude to the slaves. Because back in the day when blacks were treated so poorly, the got taken advantage of and all their right were taken away even though they had the same rights as the whites. Sorta like in The Warning when he says "There is a poor, blind Samson in this land, shorn of his strength and bound in bonds of steel."
