And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and He will teach us of His ways, and we will walk in His paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem. And He shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruning hooks: nation shall not lift up sword against nation, neither shall they learn war any more.—Isaiah 2:3–4
“… neither shall they learn war any more.”
“And I will cut off the chariot from Ephraim, And the horse from Jerusalem, And the battle bow shall be cut off, And he shall speak peace unto the nations; And his dominion shall be from sea to sea, And from the River to the ends of the earth.” Zechariah 9:10
“and He will teach us of His ways, and we will walk in His paths:”
“Her ways are ways of pleasantness, And all her paths are peace.” – Proverbs 3:17
What shall they learn, if not the Tehillim (Psalms) of David?
Singing Tehillim is unconditional love of HaShem!
A Song of Ascents; of David. I rejoiced when they said unto me: ‘Let us go unto the house of the LORD.’ Our feet are standing Within thy gates, O Jerusalem; Jerusalem, that art builded As a city that is compact together; Whither the tribes went up, even the tribes of the LORD, As a testimony unto Israel, To give thanks unto the name of the LORD. For there were set thrones for judgment, The thrones of the house of David. Pray for the peace of Jerusalem; May they prosper that love thee. Peace be within thy walls, And prosperity within thy palaces. For my brethren and companions’ sakes, I will now say: ‘Peace be within thee.’ For the sake of the house of the LORD our God I will seek thy good.
Tehillim (Psalms) 122
