John 20:8,9

JOHN—NOTE ON John 20:8 the other disciple... also went in. The presence of two male witnesses made evidence acceptable under Jewish law (see Deuteronomy 17:6; Deuteronomy 19:15). As yet they did not understand the Scripture proves that the disciples did not make up a story to fit what they thought was predicted by Scripture. Only later, aided by the Spirit’s teaching ministry (see notes on John 14:26; 16:13), were they able to understand. John may be thinking of specific OT passages (such as Psalms 16:10; Isaiah 53:10; Hosea 6:2) or of broader themes in the whole of Scripture (Luke 24:25, Luke 24:32, Luke 24:44).
