Renew one's youth

reshuffle officers and men(rig up a military force)

The source of poverty

step for step(run neck and neck)

look for an ox when one is riding it

Hide and disappear

exhort somebody to be good and guard him against evil

strain the meaning

a silent transforming influence

Be unreasonable

stay abreast of

soft living

Light death and justice

All tricks have been exhausted.

swell with self-importance

exotic and strangely scented flowers(rare flowers and grasses)

Be well-matched in strength

as light as a thistledown

empty the coffers

annoy persistently
