The Fehu rune is the first rune in the Elder Futhark, the oldest runic alphabet used by the Germanic peoples. Its name is derived from the Old Germanic word "fehu", meaning "cattle" or "wealth". The Fehu rune represents not only material wealth but also spiritual wealth, prosperity, abundance, and power.

Olde Englishe  

Feoh byþ frofur fira gehƿylcum;

sceal ðeah manna gehƿylc miclun hyt dælan

gif he ƿile for drihtne domes hleotan.

Wealth is a comfort to humans all;

but each one should deal it out abundantly,

if he wants before the Lord to chance judgement.

Norwegian

Fé vældr frænda róge;

føðesk ulfr í skóge.

causes kinsmen’s quarrel;

the wolf is reared in the forest. ONRP

Icelandic 

Fé er frænda róg ok flæðar viti ok grafseiðs gata aurum fylkir.

Wealth  is kinsmens’ quarrel

and flood-tide's token

and necromancy's road.

As seen,  The Olde Englishe poem emphasizes the importance of generosity and sharing wealth with others, as a means of earning respect and honor. The Fehu rune is not just about accumulating wealth for oneself, but also about using it to benefit others.

The later Norse and Icelandic poems suggest that wealth can be a source of conflict and strife among family members, as they compete for resources and power. The reference in the Norse to the wolf living in the forest may also suggest that wealth can bring danger and risk, just as the forest can be a wild and unpredictable place.

The Icelandic poem reinforces the idea that wealth can be a cause of conflict and division, particularly among family members. The reference to the fire of the sea may also suggest that wealth can be fleeting and unstable, subject to the unpredictable forces of nature.

Overall, the Fehu rune represents the idea of wealth and prosperity, but also the need for generosity, sharing, and caution. The different interpretations of the rune in the various Rune Poems reflect the complex and multifaceted nature of wealth in the Germanic worldview.
