Exodus 24:18
Moses entered the cloud as he went up on the mountain, and he remained on the mountain forty days and forty nights.
Moses entered the cloud

The cloud marked the manifest presence and glory of God, who had descended upon Sinai before all Israel. Moses alone was summoned to draw near in this manner, serving as covenant mediator between the holy God and the people below. The cloud both revealed and concealed God’s glory, teaching that the Lord truly makes Himself known while remaining infinitely greater than human sight can bear. Similar clouds accompany the dedication of Solomon’s temple and the transfiguration of Jesus, where the Father’s presence and authority are displayed.

Luk 9:34 While Peter was speaking, a cloud appeared…

as he went up on the mountain,

Mount Sinai was the appointed place where the Lord established His covenant with Israel and gave the law that would govern their life as His redeemed people. Moses’ ascent followed the covenant sacrifice and the elders’ earlier vision of God, confirming his unique responsibility to receive God’s commands. The mountain became the setting for divine revelation, holiness, and covenant fellowship.

Exo 34:2 Be ready in the morning, and come up on Mount Sinai…
Exo 19:20 The LORD descended to the top of Mount Sinai…

and he remained on the mountain forty days and forty nights.

During these forty days, Moses received the stone tablets, instructions for the tabernacle, the priesthood, sacrifices, and Israel’s worship. The extended period emphasized the seriousness of God’s covenant and prepared Moses to lead the nation according to God’s revealed will. Forty days also recalls later seasons of testing and preparation, including Elijah’s journey to Horeb and Christ’s fasting in the wilderness. Moses received the law on the mountain; Jesus fulfilled the law and brought His people into lasting fellowship with God.

Sin and Forgiveness
'... Forgiving iniquity and transgression and sin, and that will by no means clear the guilty....'--EXODUS xxiv. 7. The former chapter tells us of the majesty of the divine revelation as it was made to Moses on 'the mount of God.' Let us notice that, whatever was the visible pomp of the external Theophany to the senses, the true revelation lay in the proclamation of the 'Name'; the revelation to the conscience and the heart; and such a revelation had never before fallen on mortal ears. It is remarkable

The Blood of the Testament
BLOOD IS ALWAYS a terrible thing. It makes a sensitive mind shudder even to pronounce the word; but, to look upon the thing itself causes a thrill of horror. Although by familiarity men shake this off, for the seeing of the eye and the hearing of the ear can harden the heart, the instinct of a little child may teach you what is natural to us in referer to blood. How it will worry if its finger bleeds ever so little, shocked as the sight, actually there be no smart. I envy not the man whose pity would

The Blood of Sprinkling
Our apostle next tells us what we are come to. I suppose he speaks of all the saints after the death and resurrection of our Lord and the descent of the Holy Ghost. He refers to the whole church, in the midst of which the Holy Spirit now dwells. We are come to a more joyous sight than Sinai, and the mountain burning with fire. The Hebrew worshipper, apart from his sacrifices, lived continually beneath the shadow of the darkness of a broken law; he was startled often by the tremendous note of the

Things Pertaining to the Kingdom.
"Now is there solemn pause in earth and heaven; The Conqueror now His bonds hath riven, And Angels wonder why He stays below; Yet hath not man his lesson learned, How endless love should be returned." Hitherto our thoughts about "The Kingdom of Heaven" have been founded on the teaching of the King respecting His Kingdom recorded in the Gospels. But we must not forget to give attention to the very important time in the life of our Lord extending between His Resurrection and Ascension, during which

The Last Supper
189. On Thursday Jesus and his disciples returned to Jerusalem for the last time. Knowing the temper of the leaders, and the danger of arrest at any time, Jesus was particularly eager to eat the Passover with his disciples (Luke xxii. 15), and he sent two of them--Luke names them as Peter and John--to prepare for the supper. In a way which would give no information to such a one as Judas, he directed them carefully how to find the house where a friend would provide them the upper room that was needed

Brief Outline of Ancient Jewish Theological Literature
The arrangements of the synagogue, as hitherto described, combined in a remarkable manner fixedness of order with liberty of the individual. Alike the seasons and the time of public services, their order, the prayers to be offered, and the portions of the law to be read were fixed. On the other hand, between the eighteen "benedictions" said on ordinary days, and the seven repeated on the Sabbaths, free prayer might be inserted; the selection from the prophets, with which the public reading concluded--the

Appendix xii. The Baptism of Proselytes
ONLY those who have made study of it can have any idea how large, and sometimes bewildering, is the literature on the subject of Jewish Proselytes and their Baptism. Our present remarks will be confined to the Baptism of Proselytes. 1. Generally, as regards proselytes (Gerim) we have to distinguish between the Ger ha-Shaar (proselyte of the gate) and Ger Toshabh (sojourner,' settled among Israel), and again the Ger hatstsedeq (proselyte of righteousness) and Ger habberith (proselyte of the covenant).

Exodus
The book of Exodus--so named in the Greek version from the march of Israel out of Egypt--opens upon a scene of oppression very different from the prosperity and triumph in which Genesis had closed. Israel is being cruelly crushed by the new dynasty which has arisen in Egypt (i.) and the story of the book is the story of her redemption. Ultimately it is Israel's God that is her redeemer, but He operates largely by human means; and the first step is the preparation of a deliverer, Moses, whose parentage,
