Verse 1
John 15:1
I am ... 7th and last "I am" statement.
husbandman ... vinedresser, gardener, - farmer, "a land worker, a tiller of the soil" - not just vinedresser. One responsible for vines in 1st century.
The imagery alludes to OT depictions of Israel as Yahweh’s vineyard (Isaiah 5:1-7 Psalms 80:8-9). Jesus replaces Israel as the central focus of Yahweh’s plan of salvation, fulfilling the role of Israel as the true vine.
