Markus 2:5

2:5 When Jesus saw their ¹  faith, he said to the paralytic, “Son, your sins are forgiven.” ² 

Markus 3:28

3:28 I tell you the truth, ³  people will be forgiven for all sins, even all the blasphemies they utter. ⁴ 

[2:5]  ¹ sn The plural pronoun their makes it clear that Jesus was responding to the faith of the entire group, not just the paralyzed man.

[2:5]  ² sn The passive voice here is a divine passive (ExSyn 437). It is clear that God does the forgiving.

[3:28]  ³ tn Grk “Truly (ἀμήν, amhn), I say to you.”

[3:28]  ⁴ tn Grk “all the sins and blasphemies they may speak will be forgiven the sons of men.”
