Passage
But thou hast not called upon me, O Jacob; but thou hast been weary of me, O Israel.
But thou hast not called upon me, O Jacob; but thou hast been weary of me, O Israel.
Isaiah 43:20 The beast of the field shall honour me, the dragons and the owls: because I give waters in the wilderness, and rivers in the desert, to give drink to my people, my chosen.
Isaiah 43:21 This people have I formed for myself; they shall shew forth my praise.
Isaiah 43:22 But thou hast not called upon me, O Jacob; but thou hast been weary of me, O Israel.
Isaiah 43:23 Thou hast not brought me the small cattle of thy burnt offerings; neither hast thou honoured me with thy sacrifices. I have not caused thee to serve with an offering, nor wearied thee with incense.
Isaiah 43:24 Thou hast bought me no sweet cane with money, neither hast thou filled me with the fat of thy sacrifices: but thou hast made me to serve with thy sins, thou hast wearied me with thine iniquities.
The verse centers on "called", "thou", "hast", "upon", "jacob", and "been". It is saying that the verse draws attention to "called" and "thou", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 21's "This people have I formed for myself..." into verse 23's "Thou hast not brought me the small...", so "called" and "thou" belong inside that flow. In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "called" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
