New Defender's Study Bible Notes
36:29 spreading of the clouds. Just how a cloud spreads out from a small cloudlet to become a cloud-covered sky is not fully understood by meteorologists even today.
36:29 the noise of his tabernacle. The usual words for “noise” and “tabernacle” are not used here. The word for noise refers to a sudden crashing noise (evidently thunder associated with the thick cloudbanks) and the tabernacle is something like a specially built lair, from which the sudden attack can be launched.
