Final answer:
After Judas threw down the thirty pieces of silver in the temple, he departed and went to River. The answer is 4) the river.
Step-by-step explanation:
According to Matthew 27:5, after throwing down the thirty pieces of silver, Judas went out and hanged himself. The Greek word used for "went out" (εξήλθεν) suggests that he left the temple and went to a place outside. The most likely place for him to have gone is the river, as it was a common place for people to go to commit sui cide in that time and place.
The other options are not as likely. Judas would not have gone to the market or his home, as he would have been afraid of being caught by the authorities. He would not have gone to the synagogue, as he would have been unwelcome there.
Therefore, the most likely answer is that Judas went to the river after throwing down the thirty pieces of silver.
