(Dan. 1:12, 16), R.V. “herbs,” vegetable food in general.
Smith's Bible Dictionary (1863)
(seeds) usually means peas, beans and the seeds that grow in pods. In the Authorized Version it occurs only in (Lamentations 1:12,16) as the translation of words the literal meaning of which is “seeds” of any kind. Probably the term denotes uncooked grain of any kind, as barley wheat, millet, vetches, etc.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
PULSE (seeds). Our English word means peas, beans, lentiles, and the produce of similar podded plants, but in Dan 1:12, Ex 17:16 the Hebrew probably denotes vegetable food in general, and in 2 Sam 17:28 parched peas, which are still a favorite food in the East.
