John 6:30

6:30 So they said to him, “Then what miraculous sign will you perform, so that we may see it and believe you? What will you do?

John 16:18

16:18 So they kept on repeating, ¹  “What is the meaning of what he says, ²  ‘In a little while’? ³  We do not understand ⁴  what he is talking about.” ⁵ 

[16:18]  ¹ tn Grk “they kept on saying.”

[16:18]  ² tn Grk “What is this that he says.”

[16:18]  ³ tn Grk “A little while.” Although the phrase τὸ μικρόν (to mikron) in John 16:18 could be translated simply “a little while,” it was translated “in a little while” to maintain the connection to John 16:16, where it has the latter meaning in context.

[16:18]  ⁴ tn Or “we do not know.”

[16:18]  ⁵ tn Grk “what he is speaking.”
