You do not court anyone’s favor because you show no partiality. 17 Tell us then, what do you think? Is it right to pay taxes to Caesar or not?” 18 But Jesus realized their evil intentions and said, “Hypocrites! Why are you testing me? 19 Show me the coin used for the tax.” So they brought him a denarius. 20 Jesus said to them, “Whose image is this, and whose inscription?” 21 They replied, “Caesar’s.” He said to them, “Then give to Caesar the things that are Caesar’s, and to God the things that are God’s.” 22 Now when they heard this they were stunned, and they left him and went away.

However, with regard to a gift, by what means does the one who receives the gift acquire it from the giver? Is it not via this document? And yet this document is merely a shard, as a document written by gentiles is not considered a legal document according to halakha. Shmuel said: The law of the kingdom is the law, i.e., Jews must obey the laws of the state in which they live. Consequently, every form of property transfer accepted by local law is valid according to halakha as well.
