BṚHADĀRAṆYAKA UPANISHAD · 1.3.9

सा वा एषा देवता दूर् नाम ।
दूरं ह्य् अस्या मृत्युर् ।
दूरं ह वा अस्मान् मृत्युर् भवति य एवं वेद ॥

sā vā eṣā devatā dūr nāma ।
dūraṃ hy asyā mṛtyur ।
dūraṃ ha vā asmān mṛtyur bhavati ya evaṃ veda ॥

That deity was called Dûr, because Death was far (dûran) from it. From him who knows this, Death is far off.
