[24:18]  ¹ tn The verb is a preterite with vav (ו) consecutive; here, the second clause, is subordinated to the first preterite, because it seems that the entering into the cloud is the dominant point in this section of the chapter.

[24:18]  ² sn B. Jacob (Exodus, 750) offers this description of some of the mystery involved in Moses’ ascending into the cloud: Moses ascended into the presence of God, but remained on earth. He did not rise to heaven – the ground remained firmly under his feet. But he clearly was brought into God’s presence; he was like a heavenly servant before God’s throne, like the angels, and he consumed neither bread nor water. The purpose of his being there was to become familiar with all God’s demands and purposes. He would receive the tablets of stone and all the instructions for the tabernacle that was to be built (beginning in chap. 25). He would not descend until the sin of the golden calf.

[34:28]  ³ tn These too are adverbial in relation to the main clause, telling how long Moses was with Yahweh on the mountain.

[34:28]  ⁴ tn Heb “the ten words,” though “commandments” is traditional.

[9:9]  ⁵ tn Heb “in the mountain.” The demonstrative pronoun has been used in the translation for stylistic reasons.

[4:2]  ⁶ tn Grk “and having fasted forty days and forty nights, afterward he was hungry.”

[1:13]  ⁷ sn The forty days may allude to the experience of Moses (Exod 34:28), Elijah (1 Kgs 19:8, 15), or David and Goliath (1 Sam 17:16).

[1:13]  ⁸ tn Grk “And he.”

[1:13]  ⁹ tn Grk “were serving him,” “were ministering to him.”

[4:2]  ¹⁰ tn Grk “in the desert, for forty days being tempted.” The participle πειραζόμενος (peirazomeno") has been translated as an adverbial clause in English to avoid a run-on sentence with a second “and.” Here the present participle suggests a period of forty days of testing. Three samples of the end of the testing are given in the following verses.

[4:2]  ¹¹ tn Grk “And he.” Here καί (kai) has not been translated because of differences between Greek and English style.

[4:2]  ¹² sn The reference to Jesus eating nothing could well be an idiom meaning that he ate only what the desert provided; see Exod 34:28. A desert fast simply meant eating only what one could obtain in the desert. The parallel in Matt 4:2 speaks only of Jesus fasting.

[4:2]  ¹³ tn The Greek word here is συντελεσθείσων (suntelesqeiswn) from the verb συντελέω (suntelew).
