Translation of "exertion" into Swahili

For no sooner was it known that I had them, than the most strenuous exertions were used to aget them from me.

Kwani haikuwa muda mrefu ilijulikana kwamba nilikuwa nayo, juhudi ya nguvu nyingi zaidi ilitumika ili kuyapata kutoka kwangu mimi.

Not by any exertions on his part, for there is no means of escape in the pit.

Sio kwa bidii yoyote yake, kwani hamna njia ya kuokoka kutoka katika shimo hili.
