Shoftim Chapter 3: Ehud, Eglon and Shamgar

(11) and the land had peace for forty years. When Othniel the Kenizzite died, (12) the Israelites again did what was offensive to the LORD. And because they did what was offensive to the LORD, the LORD strengthened King Eglon of Moab over Israel. (13) [Eglon] brought the Ammonites and the Amalekites together under his command, and went and defeated Israel and occupied the City of Palms. (14) The Israelites were subject to King Eglon of Moab for eighteen years. (15) Then the Israelites cried out to the LORD, and the LORD raised up a champion for them: the Benjaminite Ehud son of Gera, a left-handed man. It happened that the Israelites sent tribute to King Eglon of Moab through him. (16) So Ehud made for himself a two-edged dagger, a gomed in length, which he girded on his right side under his cloak. (17) He presented the tribute to King Eglon of Moab. Now Eglon was a very stout man. (18) When [Ehud] had finished presenting the tribute, he dismissed the people who had conveyed the tribute. (19) But he himself returned from Pesilim, near Gilgal, and said, “Your Majesty, I have a secret message for you.” [Eglon] thereupon commanded, “Silence!” So all those in attendance left his presence; (20) and when Ehud approached him, he was sitting alone in his cool upper chamber. Ehud said, “I have a message for you from God”; whereupon he rose from his seat. (21) Reaching with his left hand, Ehud drew the dagger from his right side and drove it into [Eglon’s] belly. (22) The fat closed over the blade and the hilt went in after the blade—for he did not pull the dagger out of his belly—and the filth came out. (23) Stepping out into the vestibule, Ehud shut the doors of the upper chamber on him and locked them. (24) After he left, the courtiers returned. When they saw that the doors of the upper chamber were locked, they thought, “He must be relieving himself in the cool chamber.” (25) They waited a long time; and when he did not open the doors of the chamber, they took the key and opened them—and there their master was lying dead on the floor! (26) But Ehud had made good his escape while they delayed; he had passed Pesilim and escaped to Seirah. (27) When he got there, he had the ram’s horn sounded through the hill country of Ephraim, and all the Israelites descended with him from the hill country; and he took the lead. (28) “Follow me closely,” he said, “for the LORD has delivered your enemies, the Moabites, into your hands.” They followed him down and seized the fords of the Jordan against the Moabites; they let no one cross. (29) On that occasion they slew about 10,000 Moabites; they were all robust and brave men, yet not one of them escaped. (30) On that day, Moab submitted to Israel; and the land was tranquil for eighty years. (31) After him came Shamgar son of Anath, who slew six hundred Philistines with an ox-goad. He too was a champion of Israel.

And a man went. He was very wealthy, and the leader of the generation. He left the land of Israel for regions out of the land because of stinginess, for he was miserly toward the poor who came to press him; therefore he was punished.

There is a difference between mitmahmeiah, bosheish and eichar:
Mitmahmeiah is the opposite of haste; not hurrying and energetic, but delaying; Bosheish is to take longer than is appropriate;
Me’acheir is to be later than an appointed time.
At first they waited, delaying, for they thought he was using the washroom, and it is normal for that to cause delay. But then, when it began to take longer than the appropriate time, they opened with a key.
But Ehud fled already as “they delayed”, the length of time for delay for the appropriate time [of waiting]. He did not think they would take longer than the appropriate time, and he rushed to flee while they would delay for the appropriate time.
