Hebrews 3:4

‘For every house is built by some one; but he who built all things is God (or ‘divine’ - theos without the article).’

These words may indicate the writer’s extreme awareness that he is writing to men who were prickly about anything that might in any way diminish God. He recognises how quickly their hackles might rise because God has not been brought into the situation, and thus he adds these words. Although it was Jesus Who built the house, he assures them that he acknowledges that it is through God, for ‘He Who built all things is God.’ He wants them to see that he sets God as over all, that he does not separate Jesus in His working from God, and he then leaves them to think through how this connects with Jesus being the builder of the house, and the One described in Hebrews 1:1-3, drawing it out by a reference to His Sonship in the following verses. This necessary tact helps to confirm that he is writing to people with a Jewish background who are sensitive to anything that might somehow diminish Yahweh.
