15 Heb “you have forgotten” (so , , ).
16 Heb “and the rocky cliff of your strength you do not remember.”
17 Heb “a vine, a strange one.” The substantival adjective זָר (zar) functions here as an appositional genitive. It could refer to a cultic plant of some type, associated with a pagan rite. But it is more likely that it refers to an exotic, or imported, type of vine, one that is foreign (i.e., “strange”) to Israel.

In other versions

For you have forgotten the God of your salvation

and have not remembered the Rock of your refuge;

therefore, though you plant pleasant plants

and sow the vine-branch of a stranger,

You have forgotten God your Savior;

you have not remembered the Rock, your fortress.

Therefore, though you set out the finest plants

and plant imported vines,

For you have forgotten the God of your salvation,

and you have failed to remember

the rock of your strength;

therefore you will plant beautiful plants

and set out cuttings from exotic vines.

Why? Because you have turned from the God who can save you.

You have forgotten the Rock who can hide you.

So you may plant the finest grapevines

and import the most expensive seedlings.

For you have forgotten the God of your salvation,

and you have not remembered the rock of your refuge;

therefore you plant plants of pleasantness,

and you plant a vine of a foreigner.

Because thou hast forgotten the God of thy salvation,

And hast not been mindful of the rock of thy strength,

Therefore shalt thou plant pleasant plants,

And shalt set it with strange slips:
