A Question I Was Asked:

'Does the Old Testament Really Predict the Resurrection of Jesus after 3 Days? I Can't Find It!'

My Reply:

Start by reading Acts 2: 22-36. In this Scripture, Peter reveals that Psalm 16:9-11 is a prophecy concerning the resurrection of Christ. His body was not to see decay (corruption), in Acts 2:31. The Jews considered that 3 days was significant in that regard; in other words, after that point, the corruption of the flesh is plainly irreversible. The point is that Jesus was raised before His body started to corrupt.

Of course, we know that Lazarus was raised by Jesus after 'four days' and perhaps Jesus was showing there that there are no limits to what God can accomplish. However, 'four days' might have been a rounded-up figure (three days plus a few hours). See John 11:1-44, especially verses 17 and 39.

This is Glen Miller's summation of what the Bible Knowledge commentary says about Acts 2:25-35:

"(Acts) 2:25-35. These verses include four proofs of the Lord’s resurrection and Ascension: (a) The prophecy of Psalm 16:8-11 and the presence of David’s tomb (Acts 2:25-31), (b) the witnesses of the Resurrection (v. 32), (c) the supernatural events of Pentecost (v. 33), and (d) the Ascension of David’s greater Son (Ps. 110:1; Acts 2:34-35)…The word translated grave in verses 27 and 31 is hades, which means either the grave (as here) or the underworld of departed spirits…Peter’s point is that since David, the patriarch and prophet was dead and buried, he could not have been referring to himself in Psalm 16:8-11; hence he was writing about the Christ (“Messiah”) and His resurrection. The oath (Acts 2:30) looks back to Psalm 132:11 (cf. 2 Sam. 7:15-16). God . . . raised . . . Jesus to life, and exalted Him (cf. Acts 3:13; Phil. 2:9) to the Father’s right hand (cf. Acts 5:30-31; Eph. 1:20; Col. 3:1; Heb. 1:3; 8:1; 10:12; 12:2; 1 Peter 3:22). Thus Jesus had the authority to send the promised Holy Spirit (Acts 1:5, 8; John 14:16, 26; 15:26; 16:7), whose presence was evidenced by what they saw (“tongues of fire,” Acts 2:3) and heard (“a violent wind,” v. 2), and the apostles speaking in other languages (vv. 4, 6, 8, 11)…Just as David was not speaking of himself in Psalm 16:8-11, so in Psalm 110:1 he was not speaking of himself. David was not resurrected (Acts 2:29, 31) nor did he ascend to heaven (v. 34). The Lord is Yahweh God who spoke to my (David’s) Lord, who is Christ, God’s Son…On five occasions in Acts some of the apostles said they were witnesses of the resurrected Christ (v. 32; 3:15; 5:32; 10:39-41; 13:30-31). They knew whereof they spoke!..2:36. Here is the conclusion of Peter’s argument. The noun Lord, referring to Christ, probably is a reference to Yahweh. The same word kyrios is used of God in verses 21, 34, and 39 (cf. Phil. 2:9). This is a strong affirmation of Christ’s deity."
