John 20:9

20:9 (For they did not yet understand ¹  the scripture that Jesus ²  must rise from the dead.) ³ 

John 21:14

21:14 This was now the third time Jesus was revealed to the disciples after he was raised from the dead.

[20:9]  ¹ tn Or “yet know.”

[20:9]  ² tn Grk “he”; the referent (Jesus) has been specified in the translation for clarity.

[20:9]  ³ sn Verse 9 is a parenthetical note by the author. The author does not explicitly mention what OT scripture is involved (neither does Paul in 1 Cor 15:4, for that matter). The resurrection of the Messiah in general terms may have been seen in Isa 53:10-12 and Ps 16:10. Specific references may have been understood in Jonah 1:17 and Hos 6:2 because of the mention of “the third day.” Beyond this it is not possible to be more specific.
