“Burden” From Concise Bible Dictionary:

Besides the common use of this word, it occurs at the commencement of several prophecies; as “The burden of Babylon,” “the burden of Moab” (Isa. 13:11The burden of Babylon, which Isaiah the son of Amoz did see. (Isaiah 13:1); Isa. 15:11The burden of Moab. Because in the night Ar of Moab is laid waste, and brought to silence; because in the night Kir of Moab is laid waste, and brought to silence; (Isaiah 15:1)). The learned are not agreed as to the force of massa in such places: its natural meaning would be “a judgment that lies heavy on the people;” but some take its meaning to be “an oracle or sentence pronounced against them.” The word occurs also in Jeremiah 23:33-3833And when this people, or the prophet, or a priest, shall ask thee, saying, What is the burden of the Lord? thou shalt then say unto them, What burden? I will even forsake you, saith the Lord. 34And as for the prophet, and the priest, and the people, that shall say, The burden of the Lord, I will even punish that man and his house. 35Thus shall ye say every one to his neighbor, and every one to his brother, What hath the Lord answered? and, What hath the Lord spoken? 36And the burden of the Lord shall ye mention no more: for every man's word shall be his burden; for ye have perverted the words of the living God, of the Lord of hosts our God. 37Thus shalt thou say to the prophet, What hath the Lord answered thee? and, What hath the Lord spoken? 38But since ye say, The burden of the Lord; therefore thus saith the Lord; Because ye say this word, The burden of the Lord, and I have sent unto you, saying, Ye shall not say, The burden of the Lord; (Jeremiah 23:33‑38), where it is “the burden of the Lord.” The false prophets were not to use this expression, as if they had a message from God. If they did, it should bring judgment upon them. The same word is translated “prophecy” in Proverbs 30:11The words of Agur the son of Jakeh, even the prophecy: the man spake unto Ithiel, even unto Ithiel and Ucal, (Proverbs 30:1) and Proverbs 31:11The words of king Lemuel, the prophecy that his mother taught him. (Proverbs 31:1).

“Tribulation” From Concise Bible Dictionary:

Besides the application of this term to any time of distress, and its special reference to this dispensation, respecting which it is said, “In the world ye shall have tribulation” (John 16:3333These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world. (John 16:33))—the Lord spoke of a distinct period of distress, such as never had been, or should be again (Matt. 24:21-2921For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. 22And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened. 23Then if any man shall say unto you, Lo, here is Christ, or there; believe it not. 24For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. 25Behold, I have told you before. 26Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. 27For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be. 28For wheresoever the carcase is, there will the eagles be gathered together. 29Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: (Matthew 24:21‑29)). These verses refer to a great tribulation that shall fall upon the Jews in a future day: (compare Jer. 30:77Alas! for that day is great, so that none is like it: it is even the time of Jacob's trouble; but he shall be saved out of it. (Jeremiah 30:7) and Dan. 12:11And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book. (Daniel 12:1)). In Revelation 7:1414And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb. (Revelation 7:14) a great multitude is referred to that have come out of the great tribulation, but these are from the nations, hence this tribulation is not the same as that which will fall specially on the Jews, though both may take place at the same time. In Revelation 2:2222Behold, I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds. (Revelation 2:22) a “great tribulation” is spoken of, but it is doubtless general, and not the same as the above.
