³ tn It is difficult to determine whether the Hebrew term הֶבֶל (hevel) means “fleeting” or “useless” in this context. The imagery of quick-burning thorns under a cooking pot is ambiguous and can be understood in more than one way: (1) It is useless to try to heat a cooking pot by burning thorns because they burn out before the pot can be properly heated; (2) the heat produced by quick-burning thorns is fleeting—it produces quick heat, but lasts only for a moment. Likewise, the “laughter of a fool” can be taken in both ways: (1) In comparison to the sober reflection of the wise, the laughter of fools is morally useless: the burning of thorns, like the laughter of fools, makes a lot of noise but accomplishes nothing; (2) the laughter of fools is fleeting due to the brevity of life and certainty of death. Perhaps this is an example of intentional ambiguity.

² sn Nothing is said about the top of the altar. Some commentators suggest, in view of the previous instruction for making an altar out of earth and stone, that when this one was to be used it would be filled up with dirt clods and the animal burnt on the top of that. If the animal was burnt inside it, the wood would quickly burn. A number of recent scholars think this was simply an imagined plan to make a portable altar after the pattern of Solomon’s—but that is an unsatisfactory suggestion. This construction must simply represent a portable frame for the altar in the courtyard, an improvement over the field altar. The purpose and function of the altar are not in question. Here worshipers would make their sacrifices to God in order to find forgiveness and atonement, and in order to celebrate in worship with him. No one could worship God apart from this; no one could approach God apart from this. So too the truths that this altar communicated form the basis and center of all Christian worship. One could word an applicable lesson this way: Believers must ensure that the foundation and center of their worship is the altar, i.e., the sacrificial atonement.
