Euphrates: See verse 5.

Dug (so also An American Translation, Luther 1984) may also be translated “looked for” (Revised English Bible) or “searched” (New Jerusalem Bible). Although it is not stated in verse 5 that Jeremiah had actually buried the loincloth in the ground, it is quite possible that he did so. Or it is possible that silt from the river had in the meantime covered the garment. Either interpretation is possible. Good News Translation “found the place” and Die Bibel im heutigen Deutsch “took … from the hiding place” prefer a more general term.

For And behold, see 1.6. Here “And I saw” would fit well.

Spoiled: The linen loincloth had “rotted and could no longer be used for anything” (Die Bibel im heutigen Deutsch). Spoiled can also be rendered “ruined” (New Revised Standard Version).
