How does Celan use allusion in the poem, Late and Deep?

In this poem, Celan seems to allude to the parting of the Red Sea or perhaps even the Great Flood, and to the condemnation of Christ when, according to the New Testament, the Jewish mob took responsibility for Christ's execution on themselves and their children, and also to the darkness during the daytime that accompanied Christ's death on the cross. Additionally, "Spiteful like golden speech" might be an allusion to Hitler. It must be remembered that some allusions can be precisely attributed to the poet, and others are suggestive and indirect. This poem has some very clear allusions and some that are less certain.
