How תֵּדָֽעוּ׃ Works in Isaiah 6:9
A focused form insight on Verb - Qal - Imperfect - second person masculine plural in Isaiah 6:9.
Isaiah 6:9 - BSB
And He replied: “Go and tell this people, ‘Be ever hearing, but never understanding; be ever seeing, but never perceiving.’
The Question
How does תֵּדָֽעוּ׃ function in Isaiah 6:9?
Short Answer
תֵּדָֽעוּ׃ is a Verb - Qal - Imperfect - second person masculine plural in Isaiah 6:9. The form helps carry the warning pattern in Isaiah 6:9: perception is present, yet true understanding is withheld or resisted in the commission context. The whole passage must govern that theological claim.
What the Form Is Doing
תֵּדָֽעוּ׃ appears in Isaiah 6:9 as a Verb - Qal - Imperfect - second person masculine plural. It names the people's perceiving in the warning pattern of Isaiah's commission.
The Qal imperfect second masculine plural is addressed to the people within Isaiah's commissioned message. It belongs to the repeated pattern of hearing and seeing without true understanding, so the form should be read inside the prophetic warning context.
Why It Matters for Interpretation
The form helps carry the warning pattern in Isaiah 6:9: perception is present, yet true understanding is withheld or resisted in the commission context. The whole passage must govern that theological claim.
The form belongs to Isaiah 6's difficult commission language about perception and understanding.
Translation Effect
The imperfect form supports the perception wording, while the surrounding phrase controls how English expresses the warning pattern.
The form guide should support the public Bible reading, not replace it with a private rendering.
What It Does Not Prove
Do not derive a full word study, grammar doctrine, or doctrine of hardening from V-Qal-Imperf-2mp alone. The form identifies the occurrence-level perception phrase.
Grammar should serve context, not override it.
Do not make the imperfect label prove more than the sentence supports.
Evidence from the Form Guide
The BSB+ row for Isaiah 6:9 links the English rendering "perceiving" with תֵּדָֽעוּ׃, Strong's H3045, and the parsing label V-Qal-Imperf-2mp.
When teaching Isaiah 6:9, connect this form to the warning pattern of perception without understanding, and keep the theological claims tied to the whole commission scene.
What It Does Not Prove
- Do not derive a full word study, grammar doctrine, or doctrine of hardening from V-Qal-Imperf-2mp alone. The form identifies the occurrence-level perception phrase.
- Grammar should serve context, not override it.
- Do not make the imperfect label prove more than the sentence supports.
- Do not use the stem label by itself to settle a theological claim.
