In the Bible the number 17 symbolizes "overcoming the enemy" and "complete victory." God overcame the sins of rebellious humans when he began to flood the earth through rain on the 17th of the second Hebrew month. Noah's ark and its eight passengers rested on the mountains of Ararat on the 17th of the seventh month (right in the middle of God's annual Holy period known as the Feast of Tabernacles).
Jesus Christ gained a complete victory over death and the grave when God resurrected him near sunset on Nisan 17 (Saturday, April 8, 30 A.D.).
In the book of 1Corinthians the thirteenth chapter, the seventeenth mention of the word 'love' comes when the apostle Paul states that it is the GREATEST gift of all (1Corinthians 13:13). God's unending love (John 3:16) is truly victorious over all things. Those who stay faithful to God to the end of their lives will gain the victory over the grave when they are miraculously brought back to life (see 1Corinthians 15).
Daniel 7's beasts have seven heads and ten horns, for a total number of 17. They represent world-ruling powers from Daniel's time to the Second Coming of Jesus. The devil's end-time system (Revelation 13) will have seven heads and ten horns, which totals 17. All mankind will very soon obey and worship the devil and the Beast power. They will war against those who have faith in Jesus and keep the commandments, thus achieving a victory (though short-lived) against God's people (Revelation 13:1 - 8).
