There are numerous references to saints in the Bible, as long as one realizes that all of these are simply to 'God's people' and especially in the New Testament to Christian believers. There are no references to saints in the sense understood by the Roman Catholic church.
Some references include the following:
2And he said, The LORD came from Sinai, and rose up from Seir unto them; he shined forth from mount Paran, and he came with ten thousands of saints: from his right hand went a fiery law for them. 3Yea, he loved the people; all his saints are in thy hand: and they sat down at thy feet; every one shall receive of thy words. 9He will keep the feet of his saints, and the wicked shall be silent in darkness; for by strength shall no man prevail.
23O love the LORD, all ye his saints: for the LORD preserveth the faithful, and plentifully rewardeth the proud doer. 52And the graves were opened; and many bodies of the saints which slept arose, 32And it came to pass, as Peter passed throughout all quarters, he came down also to the saints which dwelt at Lydda.
7To all that be in Rome, beloved of God, called to be saints: Grace to you and peace from God our Father, and the Lord Jesus Christ. 1Paul, an apostle of Jesus Christ by the will of God, to the saints which are at Ephesus, and to the faithful in Christ Jesus:
26Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints: 12Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
