Ps. 22.2 LXX

[CMatthiasT88]

εἰς τόπον χλόης, ἐκεῖ με κατεσκήνωσεν, ἐπὶ ὕδατος ἀναπαύσεως ἐξέθρεψέ με- 22.2

Here I'd like to know what sense you would say that ἐπὶ ὕδατος is used. Locative? Instrumental?

[mwh]

Impossible to say precisely of course, but basically locative, of the environment in which he was raised. Not instrumental: “he brought me up me on water”—i.e. with water—would be plain dative.

[jeidsath]

It makes more sense in the context of the sheep being cared for by a shepherd. The shepherd has pastured and raised me in a grassy place by calm waters. This mental context explains why the LXX translator thought to use ἐξέθρεψε for a Hebrew word meaning "leads".

[Saboi]

Uses ἐκτρέφω to mean παρέχω 'of natural objects, yield, produce' and so παρέσχετο με "provided to me" and the verse should begin with νομός 'pasture' (not τόπος).

[jeidsath]

That is all nonsense. It's not τόπον, it's εἰς τόπον, and followed by the ἐκεῖ. And then you've got the ἐπὶ ὕδατος ἀναπαύσεως, which would make no sense with παρέχω.
