the deer, and where the sex matters the male: a large wild animal of the hills, clean to eat and known for its bounding speed
This is the everyday Hebrew word for a deer, and where the sex is in view it means the male, the stag, which older English Bibles call the "hart". Its partner word is the one for the female, the doe (אַיָּלָה). When Moses lists the wild animals Israel may eat, though, the word simply names the kind, the deer as a species, without pressing which sex is meant.
The deer turns up in two very different settings. In the law it is a plain practical matter. A deer is game rather than livestock, so it could be killed and eaten in any town instead of being brought to the sanctuary, and anyone could eat it, whether or not they were ritually clean at the time. It is never offered in sacrifice. It was also fine eating: deer, gazelle and roebuck are named among the meats delivered every day to Solomon's table.
In poetry the deer is almost always what someone is compared to, and each comparison turns on something a deer's body can do.
- Its long leap gives Isaiah his picture of a lame man healed and bounding.
- Its thirst in a dry season gives the psalmist his picture of longing for God.
- Its speed over broken hill country gives the Song of Songs its picture of an eager young lover coming over the mountains.
- Its collapse when the grazing fails gives Lamentations its picture of Jerusalem's leaders stumbling away with no strength left.
The gazelle (צְבִי) stands beside the deer in nearly every one of these lists and comparisons. They are not the same animal, since the gazelle is smaller and belongs to open country while the deer is the larger animal of the wooded hills, but the Bible treats them as a natural pair: both wild, both swift, both permitted as food.
