listen and repeat – nature, מַטְבֵּעַ listen and repeat – coin or currency, and to sink – לִטְבּוֹעַ listen and repeat (not to be confused with to sue – לִתְבּוֹעַ listen and repeat with a ת).What is the connection between all of these?
An image is imprinted on a coin by pressing on hot metal so that parts of the metal sink down. Likewise, the laws of nature are set down, imprinted on the world we live in.
And a currency is the going rate of a nation’s coin or basic note.
For example:
אֲנִי רוֹצֶה לִפְתּוֹחַ חֶשְׁבּוֹן מט”ח – מַטְבֵּעַ חוּץ.
I (a male) want to open a foreign currency account.
