Bilangan 23:19

23:19 God is not a man, that he should lie,

nor a human being, ¹  that he should change his mind.

Has he said, and will he not do it?

Or has he spoken, and will he not make it happen? ² 

Yohanes 17:17

17:17 Set them apart ³  in the truth; your word is truth.

Titus 1:2

1:2 in hope of eternal life, which God, who does not lie, promised before the ages began. ⁴ 

[23:19]  ¹ tn Heb “son of man.”

[23:19]  ² tn The verb is the Hiphil of קוּם (qum, “to cause to rise; to make stand”). The meaning here is more of the sense of fulfilling the promises made.

[17:17]  ³ tn Or “Consecrate them” or “Sanctify them.”

[17:17]  sn The Greek word translated set…apart (ἁγιάζω, Jagiazw) is used here in its normal sense of being dedicated, consecrated, or set apart. The sphere in which the disciples are to be set apart is in the truth. In 3:21 the idea of “practicing” (Grk “doing”) the truth was introduced; in 8:32 Jesus told some of his hearers that if they continued in his word they would truly be his disciples, and would know the truth, and the truth would make them free. These disciples who are with Jesus now for the Farewell Discourse have continued in his word (except for Judas Iscariot, who has departed), and they do know the truth about who Jesus is and why he has come into the world (17:8). Thus Jesus can ask the Father to set them apart in this truth as he himself is set apart, so that they might carry on his mission in the world after his departure (note the following verse).

[1:2]  ⁴ tn Grk “before eternal ages.”
