Charles H. Spurgeon on Psalms 48:14

Unto death, or as some explain it, at death, i.e., he will save us from it; others, over death, beyond it. But the most obvious explanation, and the one most agreeable to usage, is that which makes the phrase mean even to the end of life, or as long as we live. The idea of a future state, though not expressed, is not excluded. J. A. Alexander.
