4:13 Jesus replied, 1 “Everyone who drinks some of this water will be thirsty 2 again.
1 tn Grk “answered and said to her.”
2 tn Grk “will thirst.”
3 tn Or “who chews.” On the alternation between ἐσθίω (esqiw, “eat,” v. 53) and τρώγω (trwgw, “eats,” vv. 54, 56, 58; “consumes,” v. 57) see the note on “eats” in v. 54.
4 sn Resides in me, and I in him. Note how in John 6:54 eating Jesus’ flesh and drinking his blood produces eternal life and the promise of resurrection at the last day. Here the same process of eating Jesus’ flesh and drinking his blood leads to a relationship of mutual indwelling (resides in me, and I in him). This suggests strongly that for the author (and for Jesus) the concepts of ‘possessing eternal life’ and of ‘residing in Jesus’ are virtually interchangeable.
5 tn Or “who chews”; Grk ὁ τρώγων (Jo trwgwn). The alternation between ἐσθίω (esqiw, “eat,” v. 53) and τρώγω (trwgw, “eats,” vv. 54, 56, 58; “consumes,” v. 57) may simply reflect a preference for one form over the other on the author’s part, rather than an attempt to express a slightly more graphic meaning. If there is a difference, however, the word used here (τρώγω) is the more graphic and vivid of the two (“gnaw” or “chew”).
6 sn Notice that here the result (has eternal life and I will raise him up at the last day) is produced by eating (Jesus’) flesh and drinking his blood. Compare John 6:40 where the same result is produced by “looking on the Son and believing in him.” This suggests that the phrase here (eats my flesh and drinks my blood) is to be understood by the phrase in 6:40 (looks on the Son and believes in him).
7 tn Grk “will never be thirsty forever.” The possibility of a later thirst is emphatically denied.
8 tn Or “well.” “Fountain” is used as the translation for πηγή (phgh) here since the idea is that of an artesian well that flows freely, but the term “artesian well” is not common in contemporary English.
9 tn The verb ἁλλομένου (Jallomenou) is used of quick movement (like jumping) on the part of living beings. This is the only instance of its being applied to the action of water. However, in the LXX it is used to describe the “Spirit of God” as it falls on Samson and Saul. See Judg 14:6, 19; 15:14; 1 Kgdms 10:2, 10 LXX (= 1 Sam 10:6, 10 ET); and Isa 35:6 (note context).
