Jesus tells us to "enter through the narrow gate" and "do unto others as we would have them do unto us." But these things are not always easy, as we see when King Hezekiah is faced with a siege of Jerusalem by the King of Assyria.
Based on 2 Kings 19:9b-11, 14-21, 31-35a, 36 and Matthew 7:6, 12-14:
2 Kings
When Sennacherib heard concerning King Tirhakah of Ethiopia, ‘See, he has set out to fight against you’, he sent messengers again to Hezekiah, saying, ‘Thus shall you speak to King Hezekiah of Judah: Do not let your God on whom you rely deceive you by promising that Jerusalem will not be given into the hand of the king of Assyria. See, you have heard what the kings of Assyria have done to all lands, destroying them utterly. Shall you be delivered?
Hezekiah received the letter from the hand of the messengers and read it; then Hezekiah went up to the house of the Lord and spread it before the Lord. And Hezekiah prayed before the Lord, and said: ‘O Lord the God of Israel, who are enthroned above the cherubim, you are God, you alone, of all the kingdoms of the earth; you have made heaven and earth. Incline your ear, O Lord, and hear; open your eyes, O Lord, and see; hear the words of Sennacherib, which he has sent to mock the living God. Truly, O Lord, the kings of Assyria have laid waste the nations and their lands, and have hurled their gods into the fire, though they were no gods but the work of human hands—wood and stone—and so they were destroyed. So now, O Lord our God, save us, I pray you, from his hand, so that all the kingdoms of the earth may know that you, O Lord, are God alone.’
Then Isaiah son of Amoz sent to Hezekiah, saying, ‘Thus says the Lord, the God of Israel: I have heard your prayer to me about King Sennacherib of Assyria. This is the word that the Lord has spoken concerning him:
She despises you, she scorns you—
virgin daughter Zion;
she tosses her head—behind your back,
daughter Jerusalem.
for from Jerusalem a remnant shall go out, and from Mount Zion a band of survivors. The zeal of the Lord of hosts will do this.
‘Therefore thus says the Lord concerning the king of Assyria: He shall not come into this city, shoot an arrow there, come before it with a shield, or cast up a siege-ramp against it. By the way that he came, by the same he shall return; he shall not come into this city, says the Lord. For I will defend this city to save it, for my own sake and for the sake of my servant David.’
Sennacherib’s Defeat and Death
That very night the angel of the Lord set out and struck down one hundred and eighty-five thousand in the camp of the Assyrians; when morning dawned, they were all dead bodies. Then King Sennacherib of Assyria left, went home, and lived at Nineveh.
Matthew
‘Do not give what is holy to dogs; and do not throw your pearls before swine, or they will trample them under foot and turn and maul you.
‘In everything do to others as you would have them do to you; for this is the law and the prophets.
‘Enter through the narrow gate; for the gate is wide and the road is easy that leads to destruction, and there are many who take it. For the gate is narrow and the road is hard that leads to life, and there are few who find it.
