Allusion in Crime and Punishment
The "Image of the Beast" is an allusion to the Book of Revelations and refers to the sign of the antichrist in the Christian religion. Being made in this image, as opposed to in God's image, suggests that the person possesses sinful qualities and is undeserving of Heaven's reward of life after death.
This line is an allusion to the Biblical book of Psalms 68:2. Marmeladov uses this reference to emphasize the good qualities of Ivan Afanasyvitch, who, as we shortly learn, was willing to financially assist Marmeladov--hence the praise of his character.
The Biblical story of Noah's Ark involves Noah securing pairs of all the world's animals into the safety of his boat (ark) before God sends a flood to Earth. The head clerk Zametov likely uses this expression to mean that the building is very large and full of different people, making it difficult for anyone to have seen the murderer.
Razumihin refers to the emancipation of the serfs in 1861. Until then, many lived in bound servitude to land owners in the Russian Empire. When Tsar Alexander II emancipated the serfs, this decision was followed by a great deal of social unrest.
Similar to the "three fishes" statement at the end of the preceding chapter, Dostoevsky alludes to the Trinity---a religious symbol that groups God, Jesus, and the Holy Spirit together. This allusion reinforces the underlying themes of Christian redemption in the novel.
Raskolnikov makes an allusion to Romeo, one of the titular characters from Shakespeare's Romeo and Juliet. This makes it clear that Raskolnikov is teasing Razumihin about being in love with Dounia, since calling someone a "Romeo" implies that they are lovestruck.
Porfiry refers to the biblical story of how Jesus raised Lazarus from death. Considering the themes of redemption and rebirth in the novel as they pertain to guilt, this question is less about Porfiry's curiosity and more about Raskolnikov's belief in the possibility of redemption.
Porfiry alludes to a passage from biblical book of Matthew 7:7-8 (also found in Luke 11:9-10) to make his point that Raskolnikov ought to realize that life has meaning and is worth living. The biblical verse not only reinforces the theme of redemption in the story, but it also helps to provide context for Raskolnikov to understand that he does not have to be destined for punishment if he only seeks out forgiveness.
Raskolnikov alludes to Jesus's comment in the Garden of Gethsemane, where Jesus asked God to take a symbolic cup, or burden, away from him. By saying that he must drink the cup, Raskolnikov indicates that he is ready to accept the suffering he must face for the crime he committed.
The story of Abraham features prominently in Judaism, Christianity, Islam, and all Abrahamic religions. The choice of "age of Abraham...had not passed" in this passage in meant to invoke a feeling of the ancient and ideal past before the troubles and worries of modern civilization.
