The Aramaic verb sagu (or seghah) means to grow, increase, or multiply. It appears in Daniel 4:22 where Nebuchadnezzar's greatness is described as having "grown and reached to heaven." The word captures the idea of expanding, flourishing, and reaching one's full extent.
Nebuchadnezzar's use of sagu to describe his own greatness becomes ironic within Daniel's narrative — the king who prided himself on growth was immediately brought low, eating grass like an ox. The theology embedded here is that genuine growth comes only from God: "The LORD makes poor and makes rich; he brings low and he exalts" (1 Samuel 2:7). True increase is not self-generated pride but divine gift. This Aramaic verb quietly rebukes every Babel-building impulse in the human heart.
