What was the purpose of the sacrifices?

Ezra 8:35 (ESV)

35 At that time those who had come from captivity, the returned exiles, offered burnt offerings to the God of Israel, twelve bulls for all Israel, ninety-six rams, seventy-seven lambs, and as a sin offering twelve male goats. All this was a burnt offering to the LORD.

The animal sacrifices were made as a thanksgiving to God for his mercies and as a sin offering to acknowledge their unworthiness for such mercies.1
